    Abstract: The systems and methods disclosed herein address issues of cost and weight that prevent other threat detection systems intended to detect and identify locations of incoming munitions fire such as RPGs, anti-tank missiles, and other such weapons, from being used more broadly. Systems and methods disclosed herein relate, in part, to a portable, optical sensor that has a 360-degree horizontal field of view and a selectable vertical field of view that can cover up to 90 degrees. Variations of systems and methods discussed herein are meant for use and transport by an individual or group of individuals, and do not require significant support electronics or power supplies in excess of a typical car-battery in size and weight. Other embodiments may be vehicle mounted, or may be further enhanced to work with other detection or response systems.

    Abstract: A Midwave FLIR imaging optical apparatus has both a narrow and wide field of view. The imaging optical apparatus has a See Spot mode of operation, where a laser designator spot image is superimposed on the FLIR image in the narrow field of view. A laser rangefinder receiver path is also provided. A shared aperture collects incident radiation, which after manipulation by a plurality of optically significant surfaces, projects radiation to a detector. The imaging optical system is lightweight and compact and efficiently transmits FLIR energy and a narrow band of laser energy so that a signal due to a source outside the pass bands of interest (including solar energy) will not adversely effect operation of the imaging optical apparatus.

    Abstract: A window for utilization in the receiving of intelligence from a modulated beam of collimated light, with the window being configured to restrict the field of view of the optical system used therewith, and employing the phenomenon of total internal reflection. Such a window may be used to reject the entry of unwanted radiation, such as noise, and comprises first and second generally triangularly shaped wedges of optical material. The entry face of the first wedge is generally perpendicular to a base plane, and its rear face is disposed at an acute angle to the entry face. The entry face of the second wedge is disposed at the same angle to the base plane as the rear face of the first wedge, and the two wedges are separated by a small air gap. Preferably, the rear face of the first wedge is contoured to reject incoming radiation from a direction below the base plane, with comparable contouring of the closely adjacent faces of the first and second wedges serving to permit the entry of intelligence in the form of skew rays, thus to substantially increase the directions in which desired radiation may be admitted to the optical system.

    Abstract: An optical arrangement for use in boresighting a plurality of optical paths utilized in a missile beam guidance system, to the target trackers used therewith. A boresight module optical bed supports a plurality of retro-reflective optical assemblies in a closely spaced array, and nearby is a rotational optical assembly in which is mounted an integrated laser system for providing beam guidance to a missile. The rotational optical assembly also contains a plurality of target trackers, and in a first operational mode, the laser of the rotational assembly is successively utilized in conjunction with the retro-reflective optical assemblies in order to accurately and conveniently boresight the trackers. Thereafter, the trackers are used in the acquisition and tracking of a target, and the laser is utilized for guiding the missile to intercept the target.
