Abstract: A high speed PA camera is implemented with a photodiode array image sensor of 100×100 photodiodes. It can work both continuous-frame mode and single-frame mode, and allow video rates up to 1000 frames per second. The camera's minimum sensitivity precedes 1.5 Lux and optical dynamic range is 100 times. the PA image sensor characteristic, the design of driver timing and the video signal process are described in detail.
