很多人对液体粒子场的测量十分感兴趣,并且已有人进行了这方面的研究,但是对于液体颗粒的直径,粒子空间分布,很少有人得到较理想的结果。本文将介绍以下内容:(1)用全息术测量液体粒子场原理;(2)同轴远场拍摄光路; (3)同轴再现光路;(4)粒子场信息处理方法;(5)测量结果。最终的测量结果表明,用激光全息方法测量动态液体粒子场中的粒子直径、粒子空间分布具有迅速、准确、非接触之优点,用这一方法可以得到令人满意的结果。
Many people are very interested in the measurement of the liquid particle field, and some people have conducted research in this respect, but for the diameter of liquid particles, the spatial distribution of particles, few people get better results. This article describes the following: (1) holographic measurement of liquid particle field theory; (2) co-axial far-field shooting light path; (3) coaxial reproduction light path; (4) particle field information processing method; . The final measurement results show that the laser holographic method to measure the particle diameter in the dynamic liquid particle field has the advantages of rapid, accurate and non-contact spatial distribution. Satisfactory results can be obtained by this method.
