摘要:
A method of detecting a distortion on a surface is described. A layer of liquid crystal material is formed on the surface with molecules of the material aligned in planes parallel to the surface. The molecules in each select plane have axes aligned with one another. A phase shift of electromagnetic radiation is detected. The phase shift is due to a distortion in the alignment of the molecules out of a select plane in a region of and due to the distortion on the surface.

An ingestible image scanning pill captures high resolution images of the GI tract as it passes through. Images communicated externally have exact location determination. Image processing software discards duplicate information and stitches images together, line scan by line scan, to replicate a complete GI tract as if it were stretched out in a straight line. A fully linear image is displayed to a medical professional as if the GI tract had been stretched in a straight line, cut open, laid flat out on a bench for viewing—all without making any incisions in a live patient.
摘要:
The invented optical engines are characterized as including generally parallel planar glass plate-mounted or coated dichroic and turning mirror and light valve elements. An important topological feature of the invented optical engines is the fact that like optical elements are positioned and oriented to be coplanar, i.e. the light-splitting dichroic mirror elements are coplanar with one another, the split beam-turning mirror elements are coplanar and the light valves are coplanar. This important feature of the invention renders compact optical engines that are simply and inexpensively manufactured and maintained because the critical optical elements are in part self-aligning when like optical elements are placed in an aligning mounting structure or more preferably on a common substrate that renders them self-positioning and self-aligning relative to one another. A common white light entry region and modulated tricolor beam exit region of the invented optical engines, coupled with equal optical path lengths through the engine, permit the use of a single input pupil astigmatism correction plate near the entry region and a single output image astigmatism correction plate assembly near the exit region of the engines. The optical engines may be used along with conventional other optical elements including, for example, a white light source and an optical output stack, to render a pixel-modulated tricolor projector.
摘要:
A sensor that senses incident RF signals is provided. The sensor is capable of sensing signals in the Gigahertz (GHz) and Terahertz (THz) range. The sensor may utilize one or more cantilevers, an interferometer, or may be formed in a box-type configuration.

In one embodiment of the present invention, a liquid crystal display includes a liquid crystal cell having a liquid crystal material, and drive circuitry coupled to the liquid crystal cell to provide a low voltage signal to drive the liquid crystal cell. The low voltage signal may be a pulse width modulated signal, in one embodiment.
摘要:
An optically addressed spatial light modulator may be formed with an integrated light emitting device display. The light emitting device display may be formed of a size and cost that optimizes the overall modulator design. In addition, by integrating the modulator and display devices, the overall size of the spatial light modulator may be reduced in some embodiments.
