| Abstract: | Based on the original system, a laser pulse autotrack rece~wng system ~s aeslgnea w~m mc u~z of four-quadrant photodetector. The equipment consists of the amplifying circuit, filter circuit, A/D converter and precise stepping system. The low-power MSP430 SCM is used to control the whole system and process the data. Pulse signal is suitable to restrain the environment noise and advance the anti- interference function of system. The tracking precision of 2-Dimension displacement is up to 3 p~m, and the tracking precision of coverage angle is 0.3mrad. The research is helpful to the apphcations of laser technique. |
