Study on acousto-optic modulator in laser display;

The development and application of multi-purpose electromagnetic demonstration experimental apparatus with acoustic-optic indicator;

By introducing a new concept──direction subinterval, a midpoint algorithm is successfully uSed to realize the raster display of a cubic spline curve.

The principle and current development of conventional raster display systems are introduced,and the implementation for a new radar raster-scan display system based on the DVI technology is put forward.

Several key technologies are used to improve the stability of this display system,including model blocked design of soft & hard ware system,synchronous control of programme interrupting,and integrated data communication between computer and LED display terminal.
