Abstract
A nonblocked zero-frequency filtering technique is used to improve the in-line holographic recording of small objects at extended distances from the hologram. 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 in discussing fringe visibility, image forms, and image contrast.
