  • HOE OPTICAL SYSTEM FOR HOLOGRAPHIC SIGHT
    Publication number: 20110228366
    Abstract: An optical system for holographic sights includes a laser diode, two mirrors, a holographic optical element (HOE) and a hologram. The two mirrors direct the diverging laser beam through a folded path to reach certain cross sectional area. The HOE filters, collimates and deflects the beam. Under the illumination of a collimated beam, the hologram projects a virtual reticle image at target plane. The HOE and the hologram are mounted in parallel and have the same period to achieve diffraction match so as to eliminate the image shift.
