Abstract

Since a few years we are developing a low cost adaptive optics system for the GI2T optical interferometer. Our AO is based on a curvature sensor and a 31 actuator bimorphe mirror. We designed a wavefront sensor using an array of prisms to split the pupil image and photon counting avalanche photodiodes modules as detectors. We present here the design and the first results obtained on a test bench. This AO system will be used for the tests of a laser guide star and for observations of stars and asteroids. Latter, another system will be built to equip GI2T-Regain with two AO.
