Airborne electro-optical stable platform can isolate movement and vibration of the airframe  stabilizes the optic axis of the photoelectic detector  realize the observation and tracking for the object. It has comprehensive application value in army and cicil field. Most of present airborne platforms are analogic control system  digital control system can improve the system general performance  digital control is the development direction of platform systems. In view of the requirements of isolating disturbances and stabilizing optical axis of high-precision photoelectric guidance system  a three-axis stabilized platform system centering on the rate gyro was designed. The disturbance-isolation theory of the stabilized platform was analyzed and the control structure including multiple closed-loops was designed. At last a controller of the servo system based on TMS320F2812 DSP has been designed. Experiment results meet the technical index and precision requirement  and illustrate the practicability and effectiveness of the scheme. 2011 IEEE.

With applications in digital display  consumer electronics  medicine  automotive lighting  traffic signals  and general illumination  the light-emitting diode (LED) is the world's most efficient light source being mass produced today[1]. However  high cost is the main factor restricting widespread application of LED lighting  and the packaging is the most expensive aspect of LED products. Light emitting diodes (LED) are regarded as the most important light sources in solid-state lighting for their advantages in energy efficiency  long life  vivid colors  high reliability  environmental protection  safety and multiple applications. However  application of LEDs in projection display exist many questions such as low illuminance uniformity and low energy efficiency by reason of luminescence distribution and constructure specificity for LED  the study on application of LED in the micro-projection display and projection display is reported[2-8]. Considering the question mensioned above the rectangular CPC(Compound Parabolic Concentrator) system with three-color LED is applied in the projection display. 2009 SPIE.
