Paper Abstract

Analytical and experimentally determined performance characteristics of the Integrated Imaging Irradiance (0) Sensor are presented with emphasis on features relevant to closed-loop operation. Hardware components which were used to develop data on ultimate S/N performance of the sensor are described. Experiments performed on the 13 Sensor breadboard under computer control in which optical tilt variations in an input wavefront, induced either by an electronically controlled jitter mirror or by artificially generated atmospheric turbulence, are compensated using a Type 1 digital servo, are detailed. Other sensor features reviewed include operation in the presence of partial detector failure, and with either negative or positive contrast sources.
