用脉冲全息法观测旋风粒子场

The Determination of Cyclonic Particle Field with Off-line Holography

介绍了用离轴脉冲全息记录并再现旋风除尘器模型中粉尘粒子场分布的实验和结果,较全面地讨论了记录系统光学性质对分辨粒子场的影响。该系统最小可分辨目标信号约为5μm。

Introduced the distribution of particle field in industrial cyclonic dust-collector with off-line holography.A holographic construction system and the appropriate reconstruction system will be disscussed regarding their characteristics and performance (i.e.system resolution,system aberration and correction of aberrations,and maximal total text volume).It will be shown that by using the method described,the particle with 5μm can be captured.It is very profitable for the improvement of cyclonic dust-collector in industry.
