Time Compressed Higher Speed CAOS Imaging

For the first time, proposed and experimentally demonstrated is a time compressed higher speed CAOS (Coded Access Optical Sensor) camera. Specifically, proposed are new Code Division Multiple Access (CDMA) CAOS mode Walsh-matrix based image irradiance encoding techniques that allow faster encoding times for One Dimensional (1-D) and Two Dimensional imaging (2-D). CAOS imaging and spectrometer optical designs are introduced for engaging these faster encoding methods, including a novel 2-D folded spectrum high resolution spectrometer. Experimentally demonstrated is a 16 times faster CAOS imager for 1-D imaging. Computer simulations verify a 16 times faster 2-D image recovery via the time compressed CAOS.
