5.3 Tau CNV CMOS Sensor

The FLIR AIS Tau CNV is based on a high dynamic range Scientific CMOS (sCMOS) imager
technology. The sensor features a split readout scheme in which the top and bottom halves of the sensor
are read out independently. Each column within each half of the sensor is equipped with dual column
level amplifiers and dual analog-to-digital converters. This architecture was designed to minimize read
noise and maximize dynamic range simultaneously. The dual column level amplifier/ADC pairs have
independent gain settings, and the final image is reconstructed by combining pixel readings from both the
high gain and low gain readout channels to achieve a wide intra-scene dynamic range from such a small
pixel pitch. Micro-lenses are used to focus more of the incident light onto the exposed silicon and away
from the transistors where it can be gathered improving the quantum efficiency (QE) of the sensor.
