LOW ENERGY PORTABLE LOW-LIGHT CAMERA WITH WAVELENGTH CUTOFF
A sensor for night vision applications is provided, wherein the sensor comprises a semiconductor absorption layer of composition that limits long wavelength response cutoff to between 1.25 to 1.4µm wavelength. The selection of this cutoff frequency provides improved dark current performance, thereby requiring less cooling of the sensor. Consequently, energy consumption is reduced, as the sensor does not require active cooling, so that the sensor is particularly beneficial for mobile night vision applications where battery weight is of high importance.

Aiming sight having fixed light emitting diode (LED) array and rotatable collimator
An aiming sight includes a controller, a power supply, an LED array, and a collimator. The power supply powers the LEDs to turn-on and turn-off, and powers the collimator to rotate. The collimator rotates to different rotational positions while the controller, the power supply, and the LED array remain fixed in place. The LEDs are positioned such that one LED and the collimator are at a constant angle and separated by a constant focal distance for each collimator position. The controller controls the collimator to rotate to a collimator position to generate an aiming dot at an angular position corresponding to the collimator position. The controller turns-on the LED which is at the constant angle and separated from the collimator by the constant focal distance and turns-off the remaining LEDs such that the collimator collimates light from the turned-on LED into the aiming dot at the angular position corresponding to the collimator position.
A fused thermal and a direct view aiming sight includes an optical gun sight, a thermal sight, and a beam combiner. The optical sight generates a direct view image of an aiming point or reticle superimposed on a target scene. The thermal sight generates a monochromic thermal image of the target scene. The combiner is positioned behind a 1× non-magnified optical sight and the thermal sight and in front of an exit pupil of the thermal sight. The combiner is positioned right behind the intermediate image plane of a magnified optical sight between an objective lens and an eyepiece. The combiner passes the direct view image and reflects the thermal image to the exit pupil to fuse the thermal image onto the direct view image for an operator to see at the exit pupil as a combined thermal and direct view optical image of the target scene together with the aiming reticle.

A low profile holographic sight includes a base having a mounting mechanism and a body mounted on the base for housing a laser diode, an associated electronic control and power source, and optical elements including a collimator, a transmission image hologram of the reticle pattern, and a reflective diffraction grating, wherein the optical elements are arranged within the body to direct and fold the laser beam in a substantially generally horizontal path, and is insensitive to drift in laser wavelength. The optical elements superimpose an image of the reticle pattern over the direct view of the target scene in a generally parallel and close relationship with the barrel of a firearm, such as a shotgun or a rifle, upon which the sight is mounted.
Backthinning in an area selective manner is applied to CMOS imaging sensors 12 for use in electron bombarded active pixel array devices. A further arrangement results in an array of collimators 51 aligned with pixels 42 or groups of pixels of an active pixel array providing improved image contrast of such image sensor. Provision of a thin P-doped layer 52 on the illuminated rear surface provides both a diffusion barrier resulting in improved resolution and a functional shield for reference pixels. A gradient in concentration of P-doped layer 52 optimizes electron collection at the pixel array.
