Laser display is a new type of display method. It becomes an important application of laser technology in entertainment and performance because of its so many particular virtues, Galvanometer scanning laser display is a widely adopted scanning method.This thesis consists of the following parts, including analysis of galvanometer scanner servo control system in theory, circuit design of galvanometer scanner servo control system, hardware design of imagine control system and software design of imagine display system.Galvanometer scanner servo control system includes scanning motor attached scanning mirror, servo circuit and angle detector. In this thesis, the operating mechanism and construction are analyzed. The relation between rotation angle and driving voltage based on the motor moment balance law and the armature voltage law is inferred. The motor mathematical modeling is build., The control system is confirmed according to the mathematical model, it include dual loops feedback construction, one is position feedback loop,another is current feedback loop.Display control system consists of the following parts, including microcomputer, DAC, OP amplifier and imagine display. The data of the imaging is disposed through the microcomputer. The data is converted from digit to analog by DAC and OP amplifier. The acquisition of the imaging data is by the software.Finally, the servo control circuit is the realization of the theory model and includes some assistant circuits. Powered by experiment facility, the circuit of the servo control system reaches the request of dynamic response and satisfies the need of laser displaying application...
