Fourier transform holography using a quasimonochromatic incoherent source.

Fourier transform hologram of an object is recorded using a quasimonochromatic incoherent source. The object lies in the far field of the incoherent source and is illuminated in partially coherent light. The hologram is constituted by a large number of elementary holograms, each one reconstructing only a small region of the object. The hologram as a whole reconstructs the complete object. The bias problem encountered in incoherent holography is partly resolved though at the expense of resolution.
