Abstract

A non blocked zero frequency filtering technique is used for improving the holographic recording of small objects. Since the filter is coated on the relay lens, the irradiance distributions in three planes (i.e., in projected images, diffraction patterns and reconstructed images) are calculated. Influences of filter diameter, filter transmittance and exposure level of holograms are considered for discussing the image forms and their contrast.
