Abstract

An alternative application of the Fourier transform spectroscopy (FTS) principles and techniques is proposed. Registration of hyperspectral holograms in incoherent light by using FTS is suggested. This work generalizes and develops our previous results on registration of hyperspectral Fresnel’s and image plane holograms. Theoretical and experimental results are provided and discussed. The proposed method is applied to the problems of digital holographic microscopy, including speckle noise reduction, hyperspectral imaging, and coloring and optical profiling. A major advantage of the proposed method is that it allows simultaneous recovery of the amplitude, the phase, and the spectral frequency σ of the wave field in a single registration process.
