Detuned interference filters as Fourier processors can be used to enhance the poor fringe contrast often encountered with in-line Fraunhofer holography of small or many far-fields-away micro-objects. The subsequent effect on the reconstructed-image irradiance distribution is described. The modified aperture-limited image shape and size, and the possible consequences on the quantitative analysis are discussed.
