A CMOS camera for a pyramid wavefront sensor (PWS) based adaptive optics system (AOS) is proposed in this paper. The designed camera has four 32 x 32 active reset pixel arrays with a common addressing to produce synchronous analogue outputs. The custom CMOS sensor has a layout area of 12.6 sq. mm, has a pixel fill factor of 56% and was fabricated using Austria Micro Systems 0.35 μm C35B4 CMOS process. The sensor consumes about 56 mW of power during the readout. The camera chip is enclosed in a box of dimensions 6 cm x 5.5 cm x 5 cm, which makes it suitable for use in an optical system. A high speed camera reading system has been developed that can read up to 1000 frames/second. The camera exhibits a quantum efficiency of 0.24 and the estimated minimum detectable flux is 8.69 nW/mm2on the surface of the sensor. The complete camera system detects the four pupil images produced by the PWS and can be used in the AOS.
