摘　　要： 将数字全息术应用于粒子场测试,数字全息术中采用电荷耦合成像器件CCD记录全息图,采用计算机模拟再现所记录的粒子场中粒子的一些定量信息.阐述了同轴数字全息的基本概念、原理、方法及其在粒子定位测量中的应用,并进行了计算机仿真与实验研究,证明了该方法的适用性. The diffraction patterns produced by the particles are directly recorded by a conventional CCD camera. In digital holography, image reconstruction is carried out numerically on a computer by using observed hologram patterns and some quantitative information can be derived from the reconstructed images. The basic concept and procedure of digital in-line holography are shown mainly for particle location measurement and the performance test results obtained in numerical simulations and experiments are demonstrated to examine the potential of the present method.
