100000-pixel, 120-dB imager in TFA technology

A locally autoadaptive image sensor LARS II (Lokal-AutoadaptiveR Sensor) with 368/spl times/256 pixels was designed and fabricated in thin film on ASIC (TFA) technology. Every pixel contains an automatic shutter, made of 17 transistors and two capacitors on an area of 40/spl times/38.3 /spl mu/m/sup 2/, that adapts the integration time to the local intensity. This allows the capture and processing of scenes with extremely high dynamic range. For the amorphous detector system, local contrast and temperature stability are demonstrated to be excellent while the transient response is sufficient for imaging applications. Sample images shown in this paper verify the total dynamic range of 120 dB.
