Prototype self-powered camera uses off-the-shelf components

摘要

One of the major challenges faced by developers of camera systems is to reduce their size, weight and power (SWaP). This is especially important in military systems, for example, where drone payloads must be kept to a minimum. While the size and weight of today's CCD and CMOS-based imaging sensors is small, camera systems developed using them still require an external power supply. To eliminate this external power requirement, Professor Shree Nayar, director of the Computer Vision Laboratory at Colum- bia University and his colleagues Daniel Sims and Mikhail Fridberg, have developed a camera powered by the incident light falling on a photodiode array.
