摘要

High-pass filtering effects have long been noted during recording of Fourier-type holograms on a saturable medium [Collier et al., Optical Holography (Academic, New York, 1971), p. 405]. The origin of the filtering effect lies in recording an absorption hologram such that the diffraction efficiency of strong spatial frequencies is significantly reduced by the saturable nature of the film. A simple optical configuration is used to take advantage of this effect in order to reduce the depth-of-focus noise associated with particle holography. The origin of the noise is clutter produced by a field of out-of-focus particles in which the particle under scrutiny exists [Reynolds et al., The New Physical Optics Notebook: Tutorials in Fourier Optics (Society of Photo-Optical Instrumentation Engineers, Bellingham, Washington, 1989), p. 205]. A theoretical basis for the filtering is presented. Experimental results are shown. [References: 11]
