100 000-pixel, 120-dB imager in TFA technology

A locally autoadaptive image sensor LARS II (Lokal-AutoadaptiveR Sensor) wi th 368 x 256 pixels was designed and fabricated in thin film on ASIC (TFA) technology. Every pixel contains an automatic shutter, made of 17 transisto rs and two capacitors on an area of 40 x 38.3 mu m(2), that adapts the inte gration time to the local intensity. This allows the capture and processing of scenes with extremely high dynamic range, For the amorphous detector sy stem, local contrast and temperature stability is demonstrated to be excell ent while the transient response is sufficient for imaging applications. Sa mple images shown in this paper verify the total dynamic range of 120 dB.
