一种改进型双L遮断式激光光幕靶
An Improved Dual-L Laser Light Screen Target
摘要
Abstract
In this paper,aimed at the problems of large weight,weak anti-interference ability and unadjustable measuring area of the existing light curtain target,an improved dual-L laser light screen target(DLST)is designed.It can measure the velocity and coordinates of the vertical incident projectile at the same time.DLST circuit board is designed by modularization method,which can be flexibly spliced to the screen of 0.5 m × 0.5 m multiple according to user's requirement.DLST circuit board integrates custom anti-interference chip,which can dynamically adjust the magnification of the circuit,avoid the photodiode to enter saturation state,so that the light screen target has strong anti-interference ability.To test the actual performance of DLST,four types of experiments are carried out:strong light interference,coordinate,pistol and rifle.The experimental results show that the measuring accuracy of the light screen target is 5% and the measuring accuracy of the coordinate is 5 mm.关键词
