Abstract
A holographic weapon sight with a housing that has a viewing end and an opposing target end. The viewing path is defined from the viewing end to the target end. The sight has a light source that projects a light beam along a path. The sight also has a diffractive optical element (DOE) disposed in the path of the light beam, and the DOE reconstructs an image of a reticle. The sight includes a parabolic reflector that reflects the image of the reticle. The parabolic reflector may be disposed in the viewing path such that a user views a target along the viewing path through the parabolic reflector from the viewing end.
