Paper Abstract

In the NOAO IR Adaptive Optics Program, we have elected to develop a system to use the visual light from an object to sense the wavefront errors and generate the corrections re-quired to give diffraction-limited imaging in the near-IR (2-10 microns). We have evaluated the performance of a variety of possible sensor systems, computing both their ideal performance and their expected performance with available detectors. A major consideration in this evaluation is the ability of the sensor to measure mean wavefront tilts of the visual wavefront over subapertures corresponding to the (larger) IR wavefront scale lengths. We have chosen to use a Hartmann-Shack sensor with red-sensitive image intensifiers and a Reticon detector.
