Spectrally-resolved Incoherent Holography

Abstract : Spatial and spectral information holds the key for characterizing self-luminous objects and imaging fluorescence. By combining the principles of incoherent holography and Fourier spectroscopy based on van Cittert-Zernike theorem and Wiener-Khinchin theorem respectively, an interferometric method of multispectral imaging will be discussed. By measuring the spatial and temporal coherence functions using a Mach-Zehnder interferometer capable of providing a radial shear as well as a tunable optical path delay between the interfering optical fields, the recording of 3D spatial and spectral information of an incoherently illuminated object will be presented.
