Self-reference hyperspectral holographic microscopy.

Abstract

Self-reference hyperspectral holographic microscopy with an extended, spatially incoherent, polychromatic source is suggested and experimentally verified. The reference field is the zero-order Fourier component of the object filtered out by a ring-shaped mask placed in the Fourier plane of the optical system. A set of spectrally resolved complex amplitudes of the object is obtained on the basis of a standard microscope equipped with a Michelson interferometer. Experiments on registration of hyperspectral holograms confirming the validity of the proposed theoretical model are carried out.
