Abstract
A sight assembly for mounting to a weapon is provided. A holographic optical element and a light source are provided in a fixed angular configuration with respect to one another, but may be adjusted either together or individually in a horizontal or vertical direction. A mirror or lens may also be provided. An adjustment mechanism is provided where a shaft includes at least two portions wherein the two portions of the shaft of the screw have different pitch directions and/or pitch dimensions allowing for slight adjustment of the assembly. The light source is typically a vertical-cavity surface emitting laser (VCSEL). The wavelength of the VCSEL is controlled by controlling the current it is given. The assembly further allows for perceived image distance adjustment using parallax mismatch. Further, a chassis is provided for holding holographic elements.
