Optical Compressive Sensing: a new field benefiting from classical optical signal processing techniques Academic Article uri icon


  • Compressive sensing is a relatively new theory that has introduced a dramatic breakthrough in signal acquisition. In the context of imaging, it asserts that for common types of objects and with proper system design, it is possible to capture N 2-pixel images with much fewer than N 2 measurements. This implies that it is possible to capture signals with a larger space- bandwidth product than that of the system. Implementation of compressive imaging (CI) systems requires optical design that differs drastically from that for conventional imaging. Fortunately, CI design may benefit from concepts previously developed by Prof. Caulfield and others for optical signal processing.
