Аннотация
Principles of Fourier spectrometry are used for holographic imaging of microobjects in white light. It is demonstrated that a set of the output 2D interference patterns of the spectrometer that correspond to the translation of moving mirror make it possible to reconstruct amplitude and phase distributions of a microobject in an arm of the spectrometer for any spectral component of radiation. Experimental results on the reconstruction of amplitude and phase images recorded in white light are presented.
