Triple coding empowered FDMA-CDMA mode high-security CAOS camera

For the first time, to best of our knowledge, hybrid triple coding empowered frequency division multiple access (FDMA)-code (CDMA) mode coded optical sensor (CAOS) camera is demonstrated. Compared independent FDMA and CDMA modes, FDMA-CDMA has a novel high-security space-time-frequency signal encoding design for robust, faster, linear irradiance extraction at moderately high dynamic range (HDR). Specifically, this simultaneously combines HDR strength FDMA-mode fast Fourier transform (FFT) digital processing (DSP)-based spectrum analysis with signal-to-noise ratio (SNR) provided by many simultaneous CAOS pixels’ photodetection mode. In particular, demonstrated P channels provides times faster operation versus equivalent modulation (FM)-CDMA Visible band imaging experiments using digital-micromirror-device-based operating in its passive light demonstrates = 4 mode, illustrating high-quality image recovery calibrated 64 dB six-patch target FM-CDMA which limit speed, respectively. time we demonstrate dual capture capability silicon (Si) germanium (Ge) large-area point photodetectors, allowing ultraviolet–near-infrared 350–1,800 nm full spectrum.
