The simple optical design coupled with the electrically integrated array of emitters and detectors allows for simultaneous sensing of all elements of a two dimensional array, with each pixel adjusting to maximize its sensitivity. The features of SPSI can be exploited in the writing and reading interfaces of page-oriented optical memory systems. ![]() The SPSI concept has several potential applications in sensor array technology including edge detection focus and tracking sensors dynamic spotlight tracking systems tracking of objects in manufacturing and ranging. Features include intensity compression and background subtraction on every pixel. Each pixel can control its associated photodetector(s) illumination level or modulation characteristics through electronic feedback from the pixel's photodetector(s) to its emitter. The simple and compact optical design of the recently proposed smart pixels with smart illumination (SPSI) concept allows an integrated emitter and detector array to dynamically and efficiently illuminate and sense remote objects with enhanced functionality.
