| 摘 要： | 在使用区截装置的测速系统中,为了扩大靶面面积,适用于大口径的高速飞行物体的速度测量,系统采用没有反射装置的光幕做为靶面.通过理论分析了光幕探测距离的影响因素,并通过实验验证系统的实际探测性能,系统在距离镜头1300 mm处,形成一个半径为400 mm的圆形有效探测区域,面积为0.502 m<'2>.在这个范围内,直径大...

| Abstract: | In order to expand the target area,and to suit for the velocity measurement of large-caliber and high-speed flying objects,this system uses light curtain without refective devise as the target.The influence factors of detective distance are analyzed,and the actual detective performance of the system is verified through experiment.The system forms a circle field of view,an area of 0.502 mm2,with a radius of 400 mm generally at a distance of 1 300 mm from the lens.In this field of view,object of diameter grea... |
