    摘要: In one embodiment of the present invention, a method includes introducing an optical signal into a first arm and a second arm of an optical device; self-phase modulating the optical signal propagating in the first arm; and outputting a high intensity portion of the optical signal spatially separated from a low intensity portion of the optical signal. In such manner, optical signals input into the optical device may be restored via cleaning and shaping.

    摘要: Phase retardation compensation can be achieved in liquid crystal-on-silicon imagers by stress freezing a photoelastic medium. As a result, a simple, one-piece compensator for the residual birefringence of the imagers may be provided in some cases. The stress may be frozen by subjecting a photoelastic material to a desired stress and temperature regime, resulting in a material which exhibits birefringence due to a stress level which is fixed or frozen at the molecular level within the material.

    摘要: A projection display may be formed by an imager which creates a portion of each of a plurality of spatially separated segments which together make up an overall image. The imager may produce one of those segments at any given instant of time. That segment is then replicated to fill each of the segments that form the overall image area. However, the segments that correspond to locations where that image portion should not exist are filtered out so that only one image portion for the correct segment is displayed. Each of the other segments may be produced in a time sequential fashion so that sequentially the segments fill the entire image. Thus, using this technique, substantially higher resolution may be achieved from a projection display system using fewer number of pixels in the microdisplay, in some embodiments.
