Abstract

In the present work holographic interferometric beating to produce digital moiré like patterns in a well controlled digital Fourier transform holographic experiment are reported. A simple implementation of digital Fourier transform holographic setup is used to produce these patterns. This setup allows us to control some parameters like incident angle of reference beams and spatial frequency of the interferometric beating patterns. The moiré like patterns could be promising to some optical interferometric applications, including profilometry and other opto-mechanical applications.
