Abstract

We describe an adaptive optics system designed to obtain diffraction limited imaging in the near infrared (~2 microns) with the Mayall 4-meter telescope at Kitt Peak National Observatory. The basic system consists of a 55 element adaptive mirror, a 37 element Hartmann-Shack wavefront sensor, and a dedicated microprocessor for analysis of sensor data and active mirror control. This polychromatic adaptive optics system utilizes the visible radiation from a semi-stellar source, or nearby star, for wavefront sensing while imaging the near-infrared radiation on an InSb array detector. Recent laboratory tests of the working system are summarized.
