Compressed Sensing Camera

Advantages . Design enables simultaneous sensing and compression of images. . Compression is part of the analog acquisition process, so the need for data compression algorithms is eliminated. . The image or video sequence is automatically encrypted without additional computational expense. . Design is appropriate for remote sensing applications where computational power is at a premium.

Technology This invention is a new kind of imaging device or camera. The design combines advanced signal processing, micro-electro-mechanical systems (MEMS), and system-on-a-chip (SoC) design. The camera is based on new mathematics and models for imaging, namely fresh results in signal processing, in the area that is being called compressed sensing (CS). CS enables us to measure the largest coefficients of a basis expansion of an image without ever creating a pixelized version of the image. This completely bypasses the need for power-hungry operations such as pixel accumulation and data compression algorithms. In short, the camera converts the incident two-dimensional (2-D) light field directly into a compressed and encoded 1-D bit stream that can be stored or transmitted with no further processing.

Potential Applications . Infrared cameras (near, mid, and far) . Low-light cameras . Hyperspectral cameras . Soft-x-ray cameras . Gamma ray cameras
