Method for parallax control of image reconstructed from holographic sight HOE

A holographic sight permits fast choice of the aiming sign in a variety of environmental conditions. The aiming sign, the target and the place are observed simultaneously. The aiming mark doesn't require accommodation of the eyes. Position of the aiming mark in the target plane provides the shooting at the stacking of the aiming mark to the target independently on observing angle and position of the shooting. Second advantage of holographic sight is hiding of the shooter. In this paper, a design of the optical scheme for parallax control of the holographic optical element (HOE) and the holographic sight with HOE is discussed. A solution for the removal of the aiming sign parallax has been proposed. The parallax is defined as non-coincidence of the target plane and plane of the aiming sign and depends on the aberrations of the holographic optical element.
