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.
