Abstract

The field in the correlation plane of a referenceless hologram used as a matched filter is shown to be the result of interference between different components of the reconstructed and the reconstructing fields. The intensity of the unchanged parts of the field is shown to depend on the correlation between the original field, and to be described by a mutual correlation function c(x,y). Limiting cases, c(x,y) yields 0 and c(x,y) equals 1 are considered. Also considered is the case when changes in the readout fields are limited to small changes in the secondary source phases.
