Abstract
Highlighted are the linear extreme dynamic range calibrated target imaging tests of the CAOS smart camera showing a 177 dB linear dynamic range operation with an optical attenuation controlled bright laser target
Highlights
Linear Extreme Dynamic Range (XDR) imaging is required in applications where objects of interest occur in a scene with extreme brightness to weak light zones with low contrast targets of interest embedded within these extreme zones
The Coded Access Optical Sensor (CAOS) smart camera is an AC+DC camera optimized based on imaging conditions and the application
The details of the CAOS smart camera test conditions are described in ref
Summary
Linear Extreme Dynamic Range (XDR) imaging is required in applications where objects of interest occur in a scene with extreme brightness to weak light zones with low contrast targets of interest embedded within these extreme zones. Introduced and demonstrated is the Coded Access Optical Sensor (CAOS) smart camera that has the fundamentals to provide an linear XDR along with a wide spectral response, e.g., 350 nm to 2700 nm [1,2] This smart XDR camera with a linear camera response function is designed on the principles of the XDR RF multi-access wireless mobile network and operates with a variety of image access modes to suit the pixel extraction environment [3]. This camera engages the classic operations CMOS/CCD/FPA sensor to provide a “DC” mode of operation initial image and CAOS timefrequency modulated imaging modes representing the “AC” modes of operations for XDR capture.
