11 July 1979Hybrid Analog/Digital Controller For A 69-Channel Multidither Adaptive Optical System
A 69-channel controller for a multidither adaptive optical system having a supervisory computer that establishes operating mode and monitors system performance has been developed. A hybrid approach was utilized wherein analog circuits whose characteristics are adjustable by computer control are employed to process the detected multidither signal. System structure and operating modes are described. Results of electronic component testing are reported.
