What is the principle of the lens reflective film?
Reflective films can be divided into reflective metal films and fully reflective media films. The medium reflective film uses the principle of multi-beam interference. The surface of the lens is coated with high and low index multi-layer films, which can increase the synthetic range of reflected light and significantly improve the reflective film's reflective rate (which can exceed the specially optimized design of 99.9%). The reflective metal film's reflective rate is only 97%, and the stability and wear resistance of the medium film in the air are better than that of the metal film. Read more exciting novels for free
The principle diagram of the reflective sensor
The principle diagram of the reflective sensor isn't that complicated. Let me explain it to you. Generally speaking, it had a light-emitting component and a receiving component. The light-emitting component would emit light, and the light would shoot towards the target object. When the light touched the target object, it would be reflected back and then captured by the receiver. If the target object was close or the surface was reflective, the reflected light would be stronger; if the target object was far away or the surface absorbed light, the reflected light would be weaker. When the receiving component receives different intensity of reflected light, it will produce corresponding electrical signal changes. Through the analysis and processing of this electrical signal, it can determine some characteristics of the target object, such as distance, existence, and so on. This was the general situation of the reflective photo sensor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Working principle of retro reflective sensor
The retro reflective sensor is composed of a light transmitter and a light receiver. The transmitter emitted a beam of light, which was reflected and received by the receiver. When an object was detected, the object would block the light, causing the light received by the receiver to weaken or disappear. Then, according to the intensity of the light received by the receiver, it was determined whether the object was detected. This type of sensor is suitable for detecting opaque objects and is not easily disturbed by environmental light. When it was used, the light transmitter and light receiver needed to be installed on the same side, and the object was placed on the other side of the sensor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Principle of Laser Reflective Contour Detector
The laser reflective profile recognition device uses the laser triangular reflection principle. The principle was that the laser beam was magnified to form a laser line that was projected onto the surface of the measured object. The reflected light passed through the high-quality optical system and was projected onto the imaging matrix. After calculation, the distance from the sensor to the measured surface (Z-axis) and the position information along the laser line (X-axis) were obtained. In this way, high-precision three-dimensional measurement was achieved to obtain the object's profile information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of zooming in the lens?
In-lens zooming referred to the zooming of the lens in a completely enclosed environment through the lens inside the lens. The principle was based on the principle of optical zooming, which was to change the position of the focal point by moving the lens inside the lens, thereby changing the length of the focal length of the lens and the angle of view of the lens, thus realizing the zooming in and out of the image. During this process, because the zooming operation was completed inside the lens body, the lens had the advantages of dust-proof and increased stability, but it also led to the lens being longer and heavier. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The imaging principle of the car lens
The basic principle of car lens imaging was the projection of a concave lens. The light passed through the lens (equivalent to a concave lens) to form a virtual image, and then the virtual image was transmitted to the imaging module or displayed on the screen. For the vehicle camera, the light reflected from the surface of the object is incident on the LCD/LCD image sensor through the lens. The image sensor transforms the received optical signal into a digital signal and sends it to the image signal processor. The image signal processor performs image filtering and enhancement on the digital signal, and the processed image information is transmitted to the domain controller through the serializer. Finally, the image image is presented. The car panoramic camera synthesized the images provided by the four 180-degree wide-angle cameras installed on the front, back, and side of the vehicle into a bird 's-eye view of the vehicle, which was displayed on the display screen in the car. The process was to first convert the captured image signal into an electrical signal. After the digital conversion, the processor synthesized the image signal again, and finally formed a simulated bird' s-eye view through the vehicle display screen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of reflective red dot mirror?
The principle of the reflective red dot mirror was as follows: It was mainly composed of a curved beam splitter and a point light source. After the point light source was lit, the light beam shot towards the curved beam splitter in front of it. Some of them had a graticule in front of the point light source that could illuminate the pattern. The curved beam splitter had a coating that could reflect a portion of the light in parallel to the human eye. Therefore, no matter which height the scope was viewed from, it would see parallel light, causing the red dot to change according to its position. The concave surface of the light analyzer is coated with one or more layers of light film. The light emitted by the illumination system passes through the graticule and then forms a dot (or a ring or other aiming mark) on the light analyzer and reflects parallel light into the human eye. At the same time, the human eye sees the target through the light analyzer. When the aiming mark and the target overlap, the aiming is completed. Moreover, the principle of its imaging was similar to that of a mirror. It was to project the real image of the graduation pattern (dot, circle, cursors, lines, crosses, etc.) emitted by the laser onto the lens, and then reflect it into the shooter's eyes through the coating on the surface of the lens, forming a virtual image of the graduation. The red dot scope also had a built-in light source located behind the lens (near the end of the firearm user). The light source was used as the origin to project light into the lens. After the concave lens was integrated, the light entered the observer's eyes in parallel, and the target light also entered the observer's eyes in parallel. At this time, the red dot in the target mirror was aimed at the target and the trigger was pulled to hit the target. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
reflective film glue
There were many types and uses of reflective film glue. Some reflective films used two-component oil-based pressure-sensitive glue, which ensured the weather resistance of the reflective film, making it not wrinkle, not fall off, resistant to high temperatures, resistant to cold, and able to perform well in harsh weather conditions. It was widely used in highway signs, permanent traffic signs, highway contours, and other fields. The glue must be adhered to strict specifications to ensure that the glue lasted longer. There was also the reflective film glue, which was mainly used to enhance the bond firmness of the reflective bead powder on the reflective film. It was used as a transition layer. When printing the reflective film, the customer could choose to use it according to the situation, such as directly silk-printing the reflective film glue on the reflective film, and then silk-printing the hot melt glue after drying. If you want to print color, you can first print the reflective film to increase the glue, then silk-screen color, then print transparent or white background, and finally silk-screen hot melt glue. Before use, you must use Cyclohexone or slow drying water to dilute about 20%. The number of silk-screen mesh is 80 - 150 mesh. The customer can choose to silk-screen once or twice depending on the pattern and letter size. In addition, there were also red film black acryl double-sided tape and other related products used to fix car decorative strips. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflective Film, Aluminium-plated Film
Aluminium-plated film was a composite flexible packaging material formed by coating a thin layer of metallic aluminum on the surface of a plastic film using a special process. The vacuum aluminum plating method was commonly used. The aluminum was melted and evaporated at a high temperature in a high vacuum state, so that the aluminum vapor was deposited on the surface of the plastic film, giving the surface of the film a metallic luster. It had the characteristics of both plastic film and metal. It was a cheap, beautiful, high-performance, and practical packaging material. It was not suitable for outdoor exposure. Reflective film is a combination of different base materials and sol-gel glue, and the back is composite release paper. It has a strong reflective effect in outdoor exposure or rainy environments. It is mostly used in high-speed sections, ships, vehicles, road signs, etc. Different materials can be selected according to different environments. The two were different in terms of production techniques, materials, and post-production applications. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Spray reflective film classification
Inkjet reflective films are classified according to reflective performance and usage. They can be divided into high-end (such as super-reflective film, high-strength reflective film, reflective logo on the body, and reflective film on the sea), mid-end (such as reflective film on engineering machines, reflective film on license plates), and low-end (advertising reflective film). From the composition and characteristics of reflective materials, reflective spray printing cloth is composed of reflective layer and light box cloth base layer. According to the difference of reflective structure, it can be divided into standard reflective material, wide-angle reflective material and starry reflective material. The standard reflective material is reflective spray printing cloth, which has excellent and balanced quality indicators and outstanding reflective index; the wide-angle reflective material is shiny star spray printing cloth, which extends the effective reflection angle range, but the reflective degree is slightly lower than the standard type; the star-filled reflective material is the star-filled spray printing cloth, which has the effect of twinkling stars when used, and the reflective degree is relatively low. It is mainly used in urban environments such as streets, shopping malls, and shops. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
