本文介绍了我们研制的“运动粒子瞬态激光全息测试仪”电子线路。该电路经严格的逻辑设计及计算,采用了10MHz时钟电路,并将1MHz的时钟信号巧妙地引入门控电路中,同时在技术上采用了行之有效的措施,消除了可能产生0.1μs的随机误差,时间间隔达到了(1~9)±0.1μs的精度,所输出的激光双脉冲能量接近,整机抗干抗能力强,一次性试验成功率高,可精确地测量雾化粒子场中的微粒的速度、形状、大小及其分布,收到了良好的使用效果。
This article describes the “moving particle transient laser holographic tester” electronic circuit we developed. The circuit by strict logic design and calculation, the use of 10MHz clock circuit, and 1MHz clock signal cleverly introduced into the gating circuit, while technically effective measures used to eliminate the possibility of 0.1μs randomly generated Error, the time interval of (1 ~ 9) ± 0.1μs accuracy, the output of the laser double pulse energy close to the whole machine strong anti-dry ability, a one-time test high success rate, can accurately measure the atomized particle field In the particle velocity, shape, size and distribution, received a good effect.
