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.
