摘要
为了解决光电探测靶在低照度环境下不能工作的问题,提出采用红外探测技术改善其低照度探测性能。利用普朗克定律,分析高速弹丸作用于探测光幕的红外辐射特性;结合探测光幕,分析高速弹丸穿越光幕的红外辐射通亮的变化;利用红外探测器的响应率,建立红外电压信号输出模型,设计红外探测放大电路与数据采集电路,通过实验,飞行弹丸穿越光幕瞬间,探测系统输出的信号明显,在小口径弹作用下,输出幅值可达1V。
The infrared technology was put forward to design the detection system of optic--electric detection fire in order to solve the problem that it cannot work at night, and improve its detection performance. According to Plank law IR, the characteristic of infrared radiation of flying projectile and the change of infrared radiation flux were analyzed when the projectile going through the detection screen, the model of output voltage was set up, and the amplificatory circuit and gather circuit were designed. Through experiment in the shooting range, the signal of the projectile going through screen is very obvious, the output value accessible 1V when the projectile is going through screen.
