Abstract

An experimental tracking system of fast steering mirror (FSM) is described in the paper. The system consists of a FSM, an E-O imaging sensor, an image processor and a host computer. Data of tilt are extracted from video signals of the imaging sensor by the image processor. These data are then led to the host computer. This computer executes the control program and leads the output control signal to the FSM through D/A converters. A PZT driving FSM is designed. The mirror diameter is 100 mm, tracking range is +/- 582 (mu) rad and the structure resonance frequency is 430 Hz. Digital PID control algorithm is used. In order to improve the characteristics of the acquired procedure, the control parameters are varied by the tracking error and time, and these parameters are self-optimized on line. Quadratic curve interpolation algorithm is used to expand the system bandwidth. The image processor is DSP based. Data of target centroid are extracted for estimating the tip-tilt. In order to reduce the processing, pyramid structure is used. Subpixel locating techniques are adopted. Close-loop experiments with RS-170 camera and a Reticon camera as sensor have been carried out separately. These experimental results are analyzed in the paper.
