Study On The Tracing Measurment System Of The Moving Target Trajectory Based On PSD

Moving target trajectory tracking measurement technique is the key component of the intelligent monitoring systems, measurement of the target state, the measurement of a moving target trajectory tracking to enhance the accuracy and analysis of intelligent monitoring system intelligent monitoring system is very critical technology, but the multi-contact mechanical measurement, its shortcomings can not be given to generate displacement-time curve, and the measurement accuracy is not high, the scope of application limitations, so that can not be achieved growingtest requirements. If you want to be more efficient in accordance with the expected implementation of the pilot project, to enhance the level of dynamic measurement technology, we need to apply the photoelectric detection technology and other high-tech methods to complete the moving target trajectory tracking measurement non-contact measurement.This paper analyzes and discusses the overall design and choice of light source moving target trajectory tracking measurement system, discusses in detail the composition and overall structure of the basic theory of optoelectronic displacement measurement principle and photoelectric position sensitive detector (PSD) work made system analysis and explanation. Based on the technical specifications of the subject of the project needs to complete the research and the preparation of the receiving optical imaging system analysis and design, and virtual instrument system. Finally, the causes and impact of key error for this system carried out a detailed analysis and explanation. After the a fine theoretical research and computing, this system is able to achieve the required accuracy of technical indicators.
