Verification of lens design
The following is the content related to the lens design verification: In the process of lens design, the lens optical path simulation technology could be used for design verification. It had many meanings: - Increase design efficiency: It can help designers quickly verify the design plan and avoid repeated modifications in the actual processing process, thus greatly improving the design efficiency. - Reduce R & D costs: Potential problems can be found in the design stage and optimized in advance, reducing the cost loss in the actual processing and testing process. - Optic performance optimization: Accurately analyze the optical performance of the lens and provide data support to the designer to improve the optical system and improve the image quality. - Extending design ideas: It helps designers to better understand the principles of light, stimulate inspiration, and expand design ideas. From the specific lens design verification examples, such as the lens design of the target detection space infrared camera, the solution of combining the image side eccentric optical path and low-temperature optical technology was proposed. The image side eccentric refraction optical system with an object side field of view of 8°×8°, an entrance pupil aperture of 265mm, and a working temperature of 200K was designed. The lens's maximum aperture was 280mm, and it adopted a multi-level scattered elastic support design. After the lens was adjusted and the image quality was confirmed at room temperature, the mechanical vibration test was carried out. The image quality was tested at 200K. The test results showed that the energy concentration of the lens reached 75% on the axis and 72% at the edge of the field of view. This was also a design verification process. In addition, in the lens testing laboratory, the lens was tested and analyzed in detail through various testing equipment and instruments. It was also a kind of verification of the lens design. The functional divisions of the laboratory included the sample receiving area (receiving the lens samples to be tested and registering them for classification), the pre-treatment area (pre-treatment such as cleaning and drying the lens), the testing area (equipped with high-precision testing equipment such as optical measuring instruments, microscopes, etc.), and the data analysis area (equipped with computers and data analysis software to process the analysis data to obtain the results). Each link worked together to ensure the accuracy and scientific nature of the lens inspection and verification. Read more exciting novels for free
The design of the shooting lens for the storefront scene
The following are some of the camera design ideas for the storefront scenes: ** 1, panoramic view ** 1. ** Purpose * - It was used to describe the overall appearance, location, and surrounding environment of the store. For example, the street where the store was located, the surrounding buildings, the signboard of the store, and whether there were parking lots and other supporting facilities. 2. ** Shooting Method ** - He could use a horizontal shooting method from across the street to ensure that the entire store and important elements were included in the picture. If you want to highlight the height of the storefront, you can use an upward angle; if you want to show the integration of the storefront and the surrounding environment, you can choose a slightly higher angle. ** 2. Mid shot ** 1. ** Purpose * - The focus was on the main parts of the store, such as the entrance of the store, the display window, or the special decorations in front of the store. This helped to attract the attention of the audience to the key areas of the store. 2. ** Shooting Method ** - Shoot from the front or diagonally in front of the store to ensure that the key parts are clearly presented. You can move the camera during the shooting process, such as pan from left to right, to show more details. ** 3. Close-up shot ** 1. ** Purpose * - It was used to focus on specific elements of the store, such as the unique logo on the store door, the main product in the window, or the welcome slogan at the door. These shots allowed the audience to get a closer look at the characteristics of the store. 2. ** Shooting Method ** - Directly aim at the target element to shoot. Pay attention to the accuracy of the focus to ensure that the image is clear. You can use a shallow depth of field to highlight the main body and blur the background. ** 4. Close-up shot ** 1. ** Purpose * - Capture the most attractive details of the store, such as the exquisite details of the goods, the unique font on the signboard, or the exquisite handle on the door. Close-ups could increase the visual impact of the scene and attract the audience's interest. 2. ** Shooting Method ** - Shoot close to the details of the target. Use the macro function (if the camera or phone supports it) to better show the tiny details. ** 5. Multi-angle lens ** 1. ** Purpose * - Shooting the storefront from different angles could provide a more comprehensive perspective and avoid visual fatigue from a single angle. At the same time, it could also show the three-dimensional structure of the storefront. 2. ** Shooting Method ** - In addition to shooting from the front, they could also shoot from the side, diagonally, or even from inside the store. For example, he could shoot the shop sign through the window and use the reflection of the glass to increase the layering of the picture. ** 6. Mirror Manipulation Technique ** 1. ** Pan Move Mirror ** - When shooting the signboard, window display, and other parts of the store, the camera could be moved slowly from left to right or from right to left so that the audience could gradually view the various elements of the store. 2. ** Roll the mirror back ** - When shooting the interior environment of the store, such as the hall or the private room, you can use the tilt mirror to show the feeling of the entire space. First, the camera focused on a part, then panned up or down, and finally panned back to show a larger spatial range. 3. ** Around the mirror ** - For some special decorations or important goods in the shop, you can use the revolving mirror to highlight their importance. Slowly move the camera around the target element, allowing the audience to look at it from all angles. ** 7. Potential for use ** 1. ** Purpose * - It added a layered and cinematic feel to the scene. 2. ** Shooting Method ** - When shooting the signboard of the shop, you could look for leaves and other things as the background, and then shoot the signboard. This would make the picture more rich. When shooting the hall environment, he could also use the background to block it and then blur it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What parameters should be provided to design the lens?
The parameters that needed to be provided when designing the lens included: 1. * * Lens-related parameters **: - The number of lenses. - The type of glass. - The radius of the lens. - The thickness of the lens. - The distance between the lenses. - The diameter of each lens. 2. * * Focus related parameters **: - The effective focal length (EFL) includes the focal length of the image (the distance from the main surface of the image to the focal point of the image) and the focal length of the object (the distance from the main surface of the object to the focal point of the object). It is necessary to pay attention to the problems of the focal length being too short or too long. For example, if the focal length is too short, it will cause the field of view to be too large. If the focal length is too long, the lens will be too long and the field of view will be too small. - Back focal length (BTL, the distance from the last side of the lens in the optical system to the image plane). - The optical focal length (FFL, the distance from the first surface of the lens in the optical system to the object surface) must be distinguished from the focal length of the mechanism. - Mechanical back focal length (FTL/FFL, the distance from the last mechanical surface of the lens group to the image surface). 3. * * Overall length of the lens **: - Total optical length (the distance from the first side of the lens to the image plane). - The total length of the mechanism (the distance from the end of the lens barrel to the image surface). 4. * * Field of view (FoV)**: Including diagonal field of view (FoV-D), horizontal field of view (FoV-H), and vertical field of view (FoV-V). It refers to the largest field of view that the lens can capture. 5. * * Joules (F/NO., relative aperture)**: The ratio of the effective focal length to the diameter of the pupil. It is used to determine the brightness of the lens. 6. * * Distortion-related parameters **: Distortion is divided into TV distortion and optical distortion. It is the off-axis phase difference. It is the difference between the height of the intersection point of the off-axis point and the main ray on the image plane and the ideal (near-axis) image plane. Distortion is a function of the field of view and has nothing to do with the aperture. 7. * * relative illumination (Ri)**: The ratio of the central illumination to the peripheral illumination. If the relative illumination is too low, problems such as blurring and color distortion will occur. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The difference between generation verification and family verification
One generation verification and pedigree verification were two different methods of genetic testing. One-generation verification referred to testing only the proband through the second-generation sequence, and then performing a one-generation verification on suspected mutations. Pedigree verification referred to the simultaneous second-generation sequence of the proband and his parents. Each mutation of the proband was compared in parallel by three people to determine whether it was consistent with co-separation. The first generation verification was mainly used to improve the accuracy of the test, while the pedigree verification could confirm whether the genetic information carried by the embryo was consistent with the known hereditary diseases in the family to prevent the disease genes from being passed on to the next generation.

Movie ticket verification
The method to check the movie tickets was very simple. First of all, you can carefully check the information on the movie ticket, including the movie name, screening time, theater name, etc., to see if they match the movie ticket you bought. Secondly, many movie tickets use the QR code technology. You can use the scanning tool on your phone or the scanning equipment provided by the theater to scan the QR code on the movie ticket. If the QR code was valid, the system would display the ticket information to prove that the movie ticket was valid. If you can't scan the QR code to check your ticket, you can ask the theater staff for help. They can verify the authenticity of your movie tickets through a computer or other specialized equipment. In addition, in order to protect your rights and interests, it is recommended that you choose formal channels when purchasing movie tickets, such as official ticketing websites, theater ticketing windows, or authorized third-party ticketing platforms. You should avoid buying movie tickets of unknown origin to avoid encountering fake tickets or other problems.
Bank photo verification
In the bank related business, photo verification was mainly used for identity verification and other purposes. For example, in terms of credit card processing, the new regulations required that after submitting basic personal information, one had to turn on the mobile phone camera and follow the prompts to complete the live scan. Then, the system would automatically match the user information stored in the public security database for verification. Only after all the procedures were passed could one successfully receive a credit card. In Singapore, major retail banks will implement Singpass Face Verification (SIFF), which uses facial scans to verify customer identity against national records. It is used to strengthen the digital token (MT) setting process for retail bank customers and trigger it in high-risk scenarios to prevent fraud. However, there were also loopholes in the bank's identity verification system. For example, security tests of some bank applications in Vietnam revealed that their identity verification system could be deceived by static images instead of accurately verifying the user's real face. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
