Devices and Equipment for Routine Mach–Zehnder Holographic Interference Experiments
9.1 Methods of Spatial Filtering Applicable to Mach–Zehnder Holographic Interference Experiments
9.1.1 Spatial Filtering for Schemes of Recording and Reconstruction
Spatial filtering methods are strongly connected to characteristics of holographic experimental schemes designed for recording and reconstructing Mach–Zehnder holograms. They accompany practically all stages of applications of the holographic experiment, mainly because of low spatial carrier frequencies of the holograms. The optical filtering is increasingly effective due to the use of one- or two-hole diaphragms, which select one or two required reconstructed waves; all others are blocked ...
