  • Infrared avalanche photodiode (APD) arrays represent a panacea for many branches of astronomy by enabling extremely low-noise, high-speed, and even photon-counting measurements at near-infrared wavelengths. We recently demonstrated the use of an early engineering-grade infrared APD array that achieves a correlated double sampling read noise of 0.73 e− in the lab, and a total noise of 2.52 e− on sky, and supports simultaneous high-speed imaging and tip-tilt wavefront sensing with the Robo-AO… CONTINUE READING
