  For the first time, demonstrated is the active-mode CAOS (i.e., Coded Access
Optical Sensor) camera. The design demonstrated uses a hybrid approach to both
optical device engagement and time-frequency CAOS mode operations.
Specifically, time-frequency modulation of both the target illumination light
source and the Digital Micromirror Device (DMD) combine to deliver the
Frequency Modulation (FM)-Code Division Multiple Access (CDMA) mode of the CAOS
camera. Using a 39.6 Klux white light 32 KHz FM LED source combined with a 1
KHz bit rate 4096 bits Walsh sequence CDMA code via the DMD, achieved is 58 x
70 CAOS pixels near 60 dB linear Dynamic Range (DR) imaging of a 36 patch
calibrated high DR white light target. Applications for the active-mode CAOS
camera are numerous and includes indoor full spectrum food inspection where a
linear DR camera can play an important role for accurate measurements.
