Paper Abstract

According to computer-generate holographic theory, a diffraction optics element used for holographic sight is designed by modified off-axis reference beam coding method. This diffraction optical element is composed by an off-axis Fresnel holographic lens. The spherical wave light from LD is parallel by this element. The light filter and compensation function of diffraction grating can also be replaced by this element. The fabrication of this diffraction optics element is not limited by the recording optic system. Mirrors and lenses are replaced by this element so that the reproducing optical path is simplified and the stability of the device is improved. A matlab program is used to simulate the hologram. Theoretical simulation results show that the precision of sight can be improved with the virtue of low aberration and high matching to holographic sighting window.
