Abstract: Techniques are disclosed for automatically bore-sighting a laser-based optical device to a weapon or other apparatus to which the optical device may be mounted (or otherwise coupled). According to certain embodiments of the invention, a reflective element such as a retro-reflector can be located on a target, and the apparatus is sighted (or otherwise oriented) to the target. While the apparatus is thus sighted, a processing unit (or other control unit) of the laser-based optical device can manipulate a laser-steering assembly to scan the field of view of a camera of the laser-based optical device with a laser to determine where, in the field of view, the reflective element is located and how the laser-steering assembly is oriented. Hill-climbing and/or other peak-detection techniques can be used to make either or both of these determinations.

Abstract: Techniques are disclosed for laser-based bore sighting, enabling wind sensing to be performed on captured images of the laser spot. Techniques can include image averaging, background subtraction, and filtering to help ensure that the Gaussian laser spot is detected in the image. Embodiments may include defining a bounding region and altering the operation of a camera such that the camera does not provide pixel data from pixels sensors corresponding pixels of outside the bounding region in subsequent image captures. Embodiments may additionally or alternatively include extracting two stereoscopic images from a single image capture.

Abstract: Systems and methods for enabling an integrated multifunction scope for optical combat identification and other uses. The functionality of Multiple Integrated Laser Engagement System (MILES) is combined with Optical Combat Identification Systems (OCIDS) or other identification as friend or foe (IFF) systems. This can provide for improved MILES performance through the utilization of a common laser transmission system and/or the use of location information systems, such as global positioning system (GPS) coordinates. According to some embodiments, various additional features may be included for use in training and/or combat environments.

Abstract: Techniques are disclosed for laser-based target locating for measuring and displaying absolute coordinates (e.g., Global Positioning System (GPS) coordinates) for a target. Techniques include determining absolute coordinates of a laser-based target locator, and using range and other measurements (e.g., compass heading, tilt, and/or the like) to determine the absolute coordinates of a target. The laser-based target locator can then display the absolute coordinates to a user. Sensors providing the other measurements may be calibrated by first determining the absolute coordinates of an optical tag, which may be optically communicated to the laser-based target locator.

Abstract: Techniques are disclosed for providing an optical assembly to provide stereoscopic images of a reflected laser spot to a camera for wind measurement. According to certain embodiments of the invention, an optical assembly can include left and right (or first and second) subassemblies having lens groups and reflective elements that cause light traveling left and right subassemblies to follow similar paths to focus on respective left and right portions of a camera. The camera can then use left and right images of reflected laser light to determine wind based on turbulence patterns in the left and right images.

Abstract: Embodiments of the present invention are directed toward a low-power, high quality compact laser source. Embodiments include an optical combiner combining the outputs of a pump laser and a Fabry-Perot seed laser into a fiber amplifier. The fiber amplifier can comprise, for example, erbium-doped fiber. Embodiments can include pulsed and continuous wave lasers, depending on desired functionality.

Abstract: This disclosure describes a compact and lightweight rifle scope display adapter configured to be affixed in front of the objective lens of a rifle scope. The display adapter includes a receptacle that enables the adapter to be electrically connected to a ballistic computer, rangefinder or other targeting mechanism. The display adapter is configured to receive aimpoint information and project illuminated symbology that is brought into focus by the rifle scope optics in such a way that the symbology appears to overlay an image of a scene on which the rifle scope is focused. The display adapter includes a casing that houses processing circuitry, a light emitting diode, polarizer, polarized beam splitter, liquid crystal on silicon imaging element and reflective element. The display adapter also includes a light bar, spherical mirror, quarter-wave plate and an additional polarized beam splitter contained within the light bar.

Abstract: Techniques are disclosed for providing the weapon-mounted optical scope that provides for wind sensing and the display a ballistic solution without the need for a separate device. Embodiments may include various additional sensors housed within the weapon-mounted optical scope to provide data for the ballistic solution calculation. Embodiments may further include a display at the input aperture rather than internally at the first-focal-plane, enabling for simpler, more cost effective embodiments. Additionally or alternatively, embodiments may include a laser, separate from the wind sensing laser, to perform range-finding functions, and/or an enhanced-image assembly.
