Abstract: 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.

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.

Abstract: A compact weapon sight has a housing with a base that is configured to mount to a weapon. The sight may have a holographic optical element (HOE) and a light source. The light source may be a vertical-cavity surface emitting laser (VCSEL) diode. The wavelength of the VCSEL may be adjusted by controlling the current drawn by the VCSEL and may include a temperature controller to keep the temperature of the light source at or above a minimum threshold temperature without using a thermoelectric cooler or a wavelength sensor.

Abstract: An adjustable holographic gun sight has a base and a carrier pivotally connected to the base. An adjustment mechanism may be adapted to pivot the carrier with respect to the base. A pair of dropouts connects the carrier to the base and the dropouts allow the carrier to pivot with respect to the base. The dropouts may be mounted to an external portion of the carrier and the base thereby provides for external adjustment of the gun sight.

Abstract: A mounting device for mounting an accessory to a rail of a weapon including a base portion, a first side portion configured to engage a first side of a rail of the weapon, and a second side portion configured to engage a second side of the rail. The first side portion has an opening defined therein. A movable clamping member is disposed in the opening in the first side portion so as to be movable between a clamping position where it secures the device to the rail and a retracted position. A clamping lever is pivotally interconnected with the first side portion for movement between an open position and a closed position. A link interconnects the clamping lever and the clamping member such that moving the lever from the open position to the closed position moves the clamping member from the retracted position to the clamping position.

Abstract: A holographic weapon sight folds for storage or to position where a portion of the sight is out of the way when not in use. Certain embodiments include a readout beam source mounted to the stationary base of the sight and the source directly illuminates a hologram plate supported in a pivotally mounted hologram support when the sight is in a position intended for use.

Abstract: A pivoting mount for a weapon accessory includes a base configured to attach to a weapon, an upper member, and a pivot shaft pivotally securing the upper member to the base. The upper member pivots between a use position and a storage position. The mount includes a first damping element disposed between the shaft and the base.
