Abstract:
An imaging system includes optics for forming an optical image, that provide a first region in the optical image that is characterized by a first range of best focus and a second region in the optical image that is characterized by a second range of best focus The first and second ranges correspond to object distance ranges that are discontiguous A sensor array converts the optical image to a data stream, and a digital signal processor processes the data stream to generate a final image.
Abstract:
The present invention provides photonic crystal devices, device components and methods for preventing transmission of electromagnetic radiation from one or more laser sources or laser modes so as to provide an optical shield for protecting a users eyes or an optical sensor. The present invention also provides dynamic photonic crystals and devices incorporating dynamic photonic crystals for optically modulating the intensity of one or more beams of electromagnetic radiation and other optical switching applications.
Abstract:
Arrayed imaging systems include an array of detectors formed with a common base and a first array of layered optical elements, each one of the layered optical elements being optically connected with a detector in the array of detectors.
