An orientation tracking system for a moving platform includes a transmitter which generates an beam having a known polarization with respect to a predefined coordinate system. The moving platform includes an ellipsometric detector capable of detecting the polarized beam when within the line-of-sight of the transmitter, and measuring its polarization state. The polarization state indicates the rotational orientation of the moving platform with respect to the predefined coordinate system. The beam could also be used to convey guidance commands to the platform.

Systems, devices, and methods including a bullet; a retroreflector array adhered to a base of the bullet, the retroreflector array having prism facets with a periodicity between 0.2 mm-2.0 mm; and a cover disposed over the retroreflector array and hermetically sealed at the base of the bullet; where the cover is disposed over the retroreflector array in a first position prior to firing, and where the cover is released from the base of the bullet in a second position after firing.

Systems, devices, and methods for determining a time of flight (TOF) of a first bullet fired from a gun to pass a target plane of a target; determining a location of an aimpoint on the target in an imager field of view (FOV) relative to a disturbed reticle at a time the first bullet is fired by the gun; determining a location of the first bullet relative to the location of the aimpoint on the target at the TOF in the imager FOV; and determining an updated location of the disturbed reticle based on a difference between the location of the first bullet and the location of the aimpoint on the target at the time the first bullet crosses the target plane and a difference between the location of the disturbed reticle and the location of the aimpoint on the target at the time the first bullet was fired.

A moving object command link system includes a transmitter which outputs a EM beam and a steering mechanism which directs the beam toward one or more objects, at least one of which is moving. The system may include a variable attenuator which modulates the average output power of the beam, and/or a divergence controller to maintain a desired beam size. The beam may be polarized, and the system may include a polarization modulator which changes the beam's polarization in accordance with a predetermined sequence and schedule. The system may include a 1&#xd7;2 switch to selectively provide the beam to one of first and second outputs. A tiltable dichroic beam splitter may be used to couple beams received from first and second objects to track cameras having respective boresights that are offset with respect to each other.

A moving platform roll sensor system comprises an ellipsometric detector capable of detecting a polarized beam within the detector's line-of-sight, and measuring the beam's polarization state, such that the polarization state indicates the rotational orientation of the moving platform with respect to a predefined coordinate system. The ellipsometric detector comprises a venetian blind component through which the polarized beam passes, arranged such that the intensity of the exiting beam varies with its incident angle with respect to the moving platform, a polarizing beamsplitter which splits the exiting beam into components having orthogonal circular polarizations, the relative intensities of which vary with the relative polarization vector of the beam, and first and second detectors which receive the first and second orthogonal circular components and generate respective outputs that vary with the intensities of their received components. The beamsplitter preferably comprises a quarter wave plate and a polarization grating.

A laser target board apparatus is provided for detecting spatial and temporal intensity distribution of high energy laser beams. The laser target board apparatus may include a panel having a plurality of openings and a plurality of optical rods placed therein. The laser target board apparatus may further have an optic fiber array positioned substantially parallel to and behind the panel and separated from the panel by a predetermined distance. At least one lens is configured to receive photons emitted from a second end of each optic fiber unit of the optic fiber array, and at least one camera is configured to detect the photons. A processor is configured to analyze temporal and spatial distribution of intensity of the received high energy laser beam based on data generated by the at least one camera.

An optical communication system may include a light transmission unit transmitting a light beam having a first polarization, a quarter waveplate to receive the light beam and to modify the light beam to have a second polarization, and a retroreflector to receive the light beam from the quarter waveplate and reflect the light beam to the quarter waveplate, which modifies the light beam to have a third polarization. The optical communication system may also include a half waveplate to modify the first polarization such that the first polarization is about 90 degrees rotated compared to the third polarization, and a polarizer to pass the light beam having the third polarization and to block most of the light beam having the first polarization.

An improved alignment device and method of use thereof that provides a simple, inexpensive and accurate leveling device that can be used by non-technical people to align a rifle scope to the bore of the rifle and set the vertical crosshair or turret axis plumb to the Earth. The device and method allows the rifle scope to be quickly, conveniently and accurately aligned such that the vertical reticle axis or elevation turret axis is projected through the center of the rifle bore. The device and method can be used to level or plumb a flat surface on the scope by first locating an edge of the device parallel to a flat surface on the rifle scope. The device has a low center of gravity that allows the device to stand inverted, resting on a flat horizontal surface.

A system for determining the spatial orientation of a movable apparatus includes at least one optical angle-of-arrival (OAOA) sensor array, each of which comprises multiple OAOA sensors arranged to provide a 360&#xb0; field-of-view (FOV). At least one sensor array is mounted on and has a known spatial relationship to a movable apparatus, the spatial orientation of which is to be determined. Point sources are located at one or more stationary positions within the FOV of at least one of the mounted arrays. An initial-north-finding/initial-vertical-finding (INF/INV) system determines the spatial orientation of at least one of the point sources. Processing circuitry coupled to the INF/INV system and the sensor arrays derives the spatial orientation of the mounted arrays&#x2014;and thereby the spatial orientation of the apparatus&#x2014;based on the angular positions of the stationary point sources detected by the mounted arrays.

A laser communication and spatial referencing system and related methods provides effective and secure non-line-of-sight communications. A laser communication and spatial referencing system includes a laser transmitter transmitting a pulsed laser beam encoded with binary communications data, and an imaging data receiver for receiving the pulsed laser beam reflecting off a reflective target. The imaging receiver decodes the binary communications data and determines the position of the laser beam. The laser communication and spatial referencing system may operate synchronously and/or asynchronously, and may include a display displaying a video image of area surrounding the target with the reflecting location superimposed on the image to provide visual identification of the target.

An optical angle of arrival measurement system uses an optical element to form at least one narrow width line on a focal plane array (FPA) which is oblique with respect to the FPA's row and column axes and which traverses at least two rows or columns along its length; forming two perpendicular narrow width lines in a cross-pattern is preferred. Interpolating the position of the lines on the FPA provides coordinates that can be used to calculate the optical angle of arrival in accordance with &#x3b8;x=A(x)&#xb7;tan(x/f), and &#x3b8;y=B(y)&#xb7;tan(y/f), where f is the focal length of the optical element, and A(x) and B(y) are parameters that account for optical distortion and other imperfections of the system. The resolution &#x3b4;&#x3b8; of the angle of arrival measurement can be improved to at least &#x3b4;&#x3b8;&#x2dc;(d/n)/f, where d is the FPA pixel width and n is the length in pixels of the imaged line.
