Abstract: This invention is an optical improvement to minerals that exhibit an image translation capability. These minerals translate an image between faces; however, the minerals exhibit considerable crosstalk between crystal fibers, which reduce image sharpness, contrast, and signal. This invention greatly reduces crystal fiber crosstalk.

Abstract: This invention is a wide field surveillance, monocentric, refractive optical system with inherent features being, non-mechanical, compact, high resolution, a field of view up to two Pi steradians solid angle. The optics design uses a single optical system and multiple flat image collection devices. Multiple fiber plates translate and map the image off of the curved image surface to the flat image collection devices. The fiber plates also act to translate the image into a larger volume as compared to the curved image surface, allowing required volume for the multiple image collection devices. This invention uses a single refractive optical system with multiple CCD or CMOS detectors. Advantages over prior art are simple optical system, rugged optics, high resolution and single optics which is easily manufactured.

Abstract: This invention is a wide field surveillance optical system with inherent features being, non mechanical, compact, high resolution, a field of view up to two pi steradians solid angle. The optics design uses a single optical system and multiple flat image collection devices. Multiple fiber plates translate the image off of the curved image surface to a plane for flat image collection devices. The fiber plates also act to translate the image into a larger volume as compared to the curved image surface, allowing required volume for the multiple image collection devices. This invention uses a single optical system with multiple CCD or CMOS detectors. Advantages over prior art are simple optical designs, rugged optics because it can be manufactured as a single piece, and wider field of view without the sacrifice of resolution.

Abstract: What is described is are two techniques to improve the efficiency of a lamp, one being energy recycling and the second being linear polarization recycling both of which can be implemented singularly or together in an incandescent or gas discharge lamp outputting an improved illumination and/or linear polarized illumination at a improved efficiency; the linear polarized lamp being desirable for use in an LCD projector and other applications requiring linear polarized illumination. The lamp utilizes one or more wasted energy recycling techniques.

Disclosed is a unique geometric configuration and positioning of optic substrates arranged as layers that cause polarization separation by radiation refraction and reflection and polarization conversion utilizing birefringent materials to convert incident radiation to a single linear polarization.

Abstract: A general service incandescent lamp including a housing with electrically conductive base (s); a transparent envelope; a radiation discriminative reflective film reflecting wasted radiation for recycling; a electrically driven filament; wherein an improvement is a new use of lightweight low thermal capacity insulator of fibrous ceramic material spatially formed to shade the lamp base from filament and/or reflected energy from a reflective film; wherein an improvement is to use the ceramic to shape the output beam to the solid angle of radiation; wherein an improvement contains a low thermal capacity insulator with candoluminescence material that when thermally exited emits radiation via candoluminescence improving the lamp's efficacy and color; wherein an improvement contains a larger optical spot size focusing requirement for the reflective mirror as compared to the spot size formed by the lamp's filament cross section, wherein an improvement is use of a polarized discriminative reflective film.
