Design of a High Precision Optical Galvanometer Driver

In Infrared Search and Track System (IRTS), the single frame imaging field of view of the plane array infrared detector is very small, which can not meet the increasing demand for wide field of view applications. The optical galvanometer has a very high cost performance in the application of lowcost and small volume. At the same time, the application is very necessary in terms of improving performance. In this paper, In order to expand its functionality and applicability, a pure analog and high-precision optical galvanometer drive controller is designed, and the current loop, speed loop and position loop are specially processed, which has high reliability and wide application range. The driver has been successfully applied in a round scanning optoelectronic system, achieving covers 360° horizontal field of view and has a clear image.
