摘要： The invention provides a diffusing plate with the angle of diffusion controllable within a desired range by use of a hologram, which is capable of presenting bright displays so that it is applicable to, for instance, a backlighting diffusing plate for liquid crystal display device. A diffusing plate 2 having an angle of diffusion θ is brought into close contact with a hologram photosensitive material 1. Then, parallel light 3 is obliquely at an angle of incidence α on the photosensitive material 1 while parallel light 4 is vertically incident on the diffusing plate 2. Thereupon, parallel light 4 is converted into diffused light 5 having an angle of diffraction θ upon passing through the diffusing plate 2. Diffused light 5 interferes with obliquely incident parallel light 3 from the opposite direction in photosensitive material 1 to produce interference fringes, thereby forming a reflection type hologram. Upon parallel illumination light on the hologram at the same angle of incidence α at which parallel light 3 strikes for recording, diffused light having the same angle of diffraction θ as that of diffused light 5 used for recording is reflected, and diffracted from this reflection type hologram.

摘要： A holographic weapon sight has a housing with a viewing end and an opposing target end, a viewing path being defined from the viewing end to the target end. A light source energized by a power source projects a light beam along a path onto a liquid crystal cell module. A power controller in communication with the power source is operable to adjust the brightness of the light beam from the light source. The liquid crystal cell module is operable to rotate and polarize the light beam to further adjust the brightness of the light beam. The light beam from the liquid crystal cell module illuminates a holographic optical element (HOE) that reconstructs an image of a reticle.
