Abstract

The data extraction and control functions of the Integrated Imaging Irradiance (0) Sensor have been implemented in software on a Data General Nova 3/12 minicomputer and used for real-time optical wavefront tilt correction. Two combinations of electronic front-end processing and software control, the faster of which can operate at information rates of up to 1 kHz, have been developed and analyzed. Critical timing considerations governing the operation of these programs in conjunction with the Data General DG/DAC analog-digital I/O interface are examined. Custom handlers which make optimal use of the DG/DAC hardware, real-time data collection and storage procedures, and off-line analysis and display software are discussed, and experimental results using the 13 Sensor optical breadboard under closed-loop computer control are presented.
