| A system (100) for directing incident sun light to a receiver (150) based on an integral imager (116) is disclosed. The system includes an imager (116) mounted to a reflector (112); a tracking controller (226) coupled to the imager; and one or more actuators (114) connected to the reflector and tracking controller. The tracking controller (226) is configured to receive and process image data from the imager (116); determine angular positions of a radiation source and target relative to the mirror normal vector (N) based on the image data; and orient the reflector with the axis bisecting the angular positions of the sun and receiver (150). When the optical axis of the imager is precisely aligned with the vector normal to the reflector, the source and target will be detected as antipodal spots (320, 330) with respect to the center of the imager's field of view, which may be used to effectively track the sun or like object. | ||||||

| 130 | Method of non-uniformity compensation (NUC) of an imager | US12259659 | 2008-10-28 | US07881495B2 | 2011-02-01 | Darin S. Williams; Edward N. Kitchen |
| The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation is performed with un-NUCed missile video, which allows boresight correlation and NUC to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager. This approach is based on the simple yet novel premise that every pixel in the array that looks at the same thing should see the same thing. As a result, the NUC terms adapt to non-uniformities in the imager and not the scene. | ||||||

| 134 | On-board light source based gain correction for semi-active laser seekers | US11139098 | 2005-05-26 | US07276681B2 | 2007-10-02 | William C. Alexander; David Schorr |
| The invention provides a method and apparatus for correcting for gain changes in detectors in a guided vehicle. In one version of the invention, an on board light source is used to generate a reference set of detector gains, which are stored in computer memory. The on board light source is then pulsed at subsequent times and the signals generated by the detectors are compared to the reference set of detector gains to determine whether any gains have changed. | ||||||
| 135 | Alignment device for a guided missile seeker | US09767971 | 2001-01-23 | US20020097391A1 | 2002-07-25 | Peter F. Perkins |
| An alignment device mounts to a missile system such that the view of a missile seeker is limited to limited fields of view at predetermined positions relative to a known reference such as the missile centerline. Once the alignment device is mounted to the missile system, an energy source emitting energy viewable by the seeker is located within a field of view. Once the seeker has locked-on to the energy source in a limited field of view, the pointing angle of the seeker can be observed by a measurement device communicating with the missile controller. Any pointing angle observed by the measurement device which differs from the known position defined by the alignment device, represents a displacement error of the seeker. Appropriate compensation is then applied to the missile controller such that alignment errors are accounted for. | ||||||
