Holographic Sight
A holographic sight has overall characteristics similar to a red dot sight. Its imaging principle is that the light emitted by the target passes through a beamsplitter and enters the human eye, allowing the human eye to see the real image of the target. The light from the illumination system that illuminates the reticle reaches the concave surface of the beamsplitter, which then reflects these light rays as parallel light into the human eye. The human eye cannot identify the true position of the reticle at this time and can only see its virtual image, which is the red dot. Moreover, it is believed that this image is at infinity. By superimposing the virtual image of this reticle with the real image of the target seen by the human eye, it can be used for aiming. Because the parallel light is reflected by the concave surface of the beamsplitter into the human eye, the human eye can see the virtual image in any direction. There is no difference from a red dot sight. The imaging principle of a true holographic sight is more complex.
FORESEEN OPTICS, based in China, has been manufacturing high-quality sniper rifle scopes since 1991 for the domestic military. In the 2000s, the company shifted to OEM production for European and American brands, incorporating advanced technologies from Russia and the U.S. FORESEEN developed FFP (First Focal Plane) scopes and large-caliber red dot scopes for the SVD, praised globally for their excellent performance and value.
