| 摘 要： | 提出了离轴滤波全息术。对圆形粒子模型,从理论上导出了再现像面上的强度分布表达式。采用数值分析技术研究了滤波器半径和吸收率对再现粒子像的强度分布的影响,获得了滤波器最佳参数选择的准则。实验结果与理论分析一致。

| Abstract: | An off-axis filtering holography is proposed in this paper.The expression of intensity distribution
in the reconstructed image plane is deduced theoretically for a model of particle with circular cross-sec-
tion.The effects of radius and absorptive index of the filter on the intensity distribution of the recon-
structed particle image are investigated using the numerical analytical technique.The criteria are ob-
tained on the optimzation of parameters of the filter.The experimental results are given and agree
with theory. |
