Abstract: A system for determining a new orientation and/or position of an object comprises a sky polarimeter configured to record image data of the sky, a signal processing unit, and logic configured to receive and store in memory the image data received from the sky polarimeter. The logic calculates the Stokes parameters (S0, S1, S2,), DoLP, and AoP from the image data, detects obscurants and filters the obscurants (such as clouds and trees) from the image data to produce a filtered image. The logic is further configured to find the Sun and zenith in the filtered image, and to determine the roll, pitch, yaw, latitude and longitude of the object using the filtered image.

Abstract: A system for display of three dimensional images and video utilizing flat panel technology, such as liquid crystal technology, wherein the left and right images are separated by polarization and the user wears polarized glasses to view the display. A first display, which may be any display technology, is used to generate an intensity modulated image. A second display is used to modulate the polarization of the intensity modulated image. A light spreading device is used to spread the light to minimize Moiré effects resulting from the use of two displays. In one embodiment, the light spreading device is a diffuser. In another embodiment, the light spreading device is a micro lens array.
