Abstract :
We propose an adjusted digital filtering method to overcome the Nyquist limitation of the iterative algorithm used to eliminate the twin image and demonstrate its advantages over existing algorithms. We also have applied and tested an electronic multiplexing method to eliminate the twin image noise in optical scanning holography
