Paper Abstract

The detector is a critical component of any Adaptive Optics WaveFront Sensing (AO WFS) system. The required performance combination of fast frame rate, high quantum efficiency, low read noise and dark signal, number and size (24-50 μm) of pixels pushes detector technology to the edge such that in many cases custom detector developments are required. This paper examines the roadmap of optical and infrared detectors by reviewing; detectors that are currently available and/or are in use in current instruments, detectors that are under development and will be used in future instruments on existing telescopes, and the requirements and status of new detectors whose development are critical for the success of the next generation of extremely large telescopes (E-ELT, GMT, and TMT). In addition, the paper will report on the AO WFS detector development and testing programs currently under way at ESO.
