Abstract

A technique using complementary sampling in the reconstruction process is proposed for speckle reduction in holographic imaging. This method would not suffer the resolution reduction experienced with the simple random sampling method that has been proposed [F. T. S. Yu and E. Wang, Appl. Opt. 12, 1656 (1973)]. Experimental results and a theoretical explanation are presented.

摘要

提出了一种在重建过程中使用互补采样的技术，用于减少全息成像中的散斑。该方法不会像已提出的简单随机采样方法[F. T. S. Yu和E. Wang，《应用光学》12, 1656 (1973)]那样经历分辨率降低的问题。给出了实验结果和理论解释。
