Application of Photoelectric Coordinate Sensors in Optical Screen

Against the problems of calibration scheme existing in automatic photoelectric target-scoring system,problems of sensitivity consistency of photoelectric receiver and mass data collection with high speed existing in infrared optical screen,LED luminescent tube with large radiation angle has been adopted.With photoelectric switching circuit and high speed sampling and holding circuit designed,photoelectric coordinate sensors based on photoelectric switch and sampling resistance network have been realized,increasing detection sensitivity and systemic consistency,reducing difficulty and cost of system design.It is validated that this method has higher precision with better prospect of application.
