Paper Abstract

SWIR image sensors based on p-i-n photodiodes arrays present a tremendous interest in applications often requiring a high intra-scene dynamics. This paper describes a single-chip InGaAs SWIR camera with more than 120 dB intrinsic operational dynamic range with an innovative CMOS ROIC technology initially developed by New Imaging Technologies for visible CMOS camera chip. A simplified camera with on chip fixed pattern noise correction is presented. We also present the next generation of focal plane arrays (FPA) based on a VGA format of 640 x 512 pixels with a pitch of 15 μm. These FPAs are associated to a logarithmic wide dynamic range ROIC. We give the electro-optics performances and particularly the visible extension capabilities. This InGaAs VGA logarithmic single-chip camera allows a high resolution SWIR camera with minimized system complexity and low power consumption.
