Abstract :

Multi-pixel imaging devices such as CCD, CMOS and FPA photo-sensors dominate the imaging world. These photodetector array (PDA) devices certainly have their merits including increasingly high pixel counts and shrinking pixel sizes, nevertheless, they are also being hampered by limitations in instantaneous linear dynamic range, inter-pixel cross-talk, quantum full well capacity, signal-to-noise ratio, sensitivity, spectral flexibility and in some cases, imager response time. Recently invented is the coded access optical sensor (CAOS) smart camera that works in unison with current PDA technology to counter fundamental limitations of PDA-based imagers while providing extreme linear dynamic range, extreme image security, extreme inter-pixel isolation and high enough imaging spatial resolution and pixel counts to match application needs. This talk describes the basics of the CAOS smart camera invention using the Texas instruments (TI) digital micromirror device (DMD). The talk highlights recent experimental demonstrations of both white light and multi-spectral CAOS-based imaging including CAOS-mode imaging over a 136 dB linear dynamic range. Novel applications of the CAOS smart camera include automotive and surveillance imaging where smartness to identify vital targets in extreme contrast scenarios is vital for both mobile and stationary system operations
