GUN SIGHT

摘要

A sight assembly for mounting to a weapon. A holographic optical element and a light source are in a fixed angular configuration with respect to one another, but may be adjusted either together or individually in a horizontal or vertical direction. The sight assembly may have a mirror or lens. 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 the assembly. The light source may be a vertical-cavity surface emitting laser (VCSEL). A temperature sensor may sense a temperature of the VCSEL. A current to the VCSEL may be adjusted based on a change in the temperature such that the output wavelength is approximately the same as a desired wavelength. The assembly may further allow for perceived image distance adjustment using parallax mismatch.

1. A compact weapon sight, comprising:
a housing having a base configured to mount to a weapon; a holographic optical element (H.O.E.), the H.O.E. supported by the housing; a light source, the light source having a laser diode operable to emit a beam of light at an output wavelength when energized, the laser diode illuminating the H.O.E. when the laser diode is energized; a power source operable to energize the laser diode; a temperature sensor for sensing a temperature of the laser diode; and an open loop wavelength controller communicating with the temperature sensor, the temperature sensor sensing and communicating the temperature of the laser diode to the wavelength controller, the controller operable to control a current from the power source to the laser diode, the controller adjusting the current based on a change in the temperature such that the output wavelength is approximately the same as a desired wavelength.
