摘要

We demonstrate a wide temperature range and high thermal sensitivity radiometry image sensor by using a 32x32 pixels SPAD imager sensor with a time gated active reset circuit. The temperature range with upper limit of 1050 °C and lower limit of 280 °C can be detected with low noise, thanks to the high sensitivity performed by short deadtime and adjustable summed output of multi-pixel readout techn...
