Paper Abstract

The development and improvement of holographic sight is continuing with better accuracy, reduced size and greater simplicity. In this work, for a given requirement, a holographic sight was designed and developed to get an optimum performance of the parameters like: range, field of view, elevation, and windage adjustments of the stable image of the reticle for zeroing in on the target. It is achieved by considering the critical aspects of optical, mechanical and electronic circuitry for controlled light output in the device. The design incorporates a laser diode light source and a pair of holographic elements (reticle and collimator) to make the sight achromatic, thus avoiding sighting errors due to laser diode wavelength drift. The complete assembly of the holographic sight consists of only four components namely, laser diode, holographic collimator, plane mirror and the reticle hologram. The virtual image of the reticle can be adjusted to coincide with the impact point of the bullet by adjusting the laser diode position.
