Product Name: Holographic Sight

Product model: 3-15x44

The full name of holographic sight is laser holographic diffraction sight, which is a revolutionary fast sight that directly observes the impact point and uses the impact point as the aiming mark. Aim fast and shoot accurately. (Holographic sight uses two points and one line of sight instead of the traditional concept of three points and one line of sight).

principle

Brief Introduction of Holographic Diffraction Sight;

1. Human eyes: Before talking about sight, we should first talk about some characteristics of human eyes, because no matter what kind of sight is to be seen by human eyes, it is difficult to explain the working principle of sight on the basis without first explaining the characteristics of human eyes. The human eye has two characteristics. First, when receiving a beam of parallel light, it will think that the light source is located at an infinite distance. At this time, the naked eye cannot directly judge the distance of the light source, for example, when we are staring at the sun or being directed by a searchlight from a long distance. Secondly, the human eye is also easily deceived. When light is reflected, refracted and re-entered into the human eye, the human eye cannot directly determine the real position of the light source, which is to see the virtual image.

2. Confusable sight (red dot principle): The characteristics of human eyes are introduced, and the principle of common reflective sight is also mentioned, so as to make a comparison with holographic diffraction sight. The following figure is a schematic structural diagram of a common reflective sight. The light emitted by the target enters the human eye through a spectroscope, and the human eye can see the real image of the target. The light from the illumination system illuminating the reticle is transmitted to the concave surface of the spectroscope, which then reflects the light into parallel light to enter the human eye. The human eye cannot recognize the real position of the reticle at this time. It can only see its virtual image, that is, the red dot, and thinks that this image is at infinity. The virtual image of the reticle and the real image of the target seen by human eyes can be superimposed to be used for aiming. And because the parallel light reflected by the concave surface of the spectroscope enters the human eye, the human eye can see the virtual image in any direction, just as you move several kilometers on the ground in a short time, and it is the same principle to see the position of the sun as before you move. On the other hand, because only the human eye can see the red dot when receiving the parallel light reflected by the spectroscope, that is to say, if you can see the red dot on a reflective sight that has been zeroed out, it means that your line of sight is parallel to the aiming line of the gun, so you only need to aim the red dot at the target to shoot.

The red dot mirror uses the reflection principle, so it can be made into red or green symbols, or red and green are exchanged, parallax always exists.

Holographic sight uses diffraction principle. The diffraction angles of red light and green light differ greatly. It is impossible to achieve the simultaneous existence of red and green differentiation. This is also the fundamental difference from the red dot mirror.

The partition image of the holographic sighting telescope shields distant objects only about one eighth of that of the red dot mirror, and high resolution is one of the outstanding advantages.

Principle of holographic sight: Those who have experience in using reflective sight and holographic diffraction, or who have played some FPS games, will think that the two are used in the same way, just aim the red dot at the target. Although the operations of the two are similar, the generating principle of the " red dot" is quite different.

As mentioned earlier, the red dot seen on the reflective sight is a virtual image formed when the light from the light source irradiates the reticle and then is reflected to the human eye via the curved surface of the spectroscope. The red dot seen on the holographic diffraction sight is the holographic image of the reticle produced by holographic imaging/visualization technology.

The screen of the holographic sight is a holographic photograph, on which all information about the amplitude and position of the transmitted light wave passing through the reticle is recorded. Of course, this reticle will not be installed in the sight. It is only used to take holographic photos when the factory produces holographic sight. The screen of the holographic sight is also a holographic photo taken of the reticle. The shooting method is as follows:

The lase emitted by that lase is divided into two beams by a optical splitter, wherein one beam passes through a len group and is collimated into parallel light, and is directly irradiated on the holographic photosensitive film as reference light; While the other beam of light is irradiated to the reticle as illumination light after passing through the transparent part of the reticle, then corrected into parallel light by the lens, and finally irradiated to the holographic photosensitive film, thus completing the shooting of the holographic image of the reticle. During the shooting process, there are strict requirements for the position and angle of each original in the whole optical path system.
