Interferography: a passive coherence spectral imaging for three-dimensional distributions of polychromatic light sources

摘要

Like a volume holography reproduces color images of three-dimensional(3D) objects, it is possible to obtain simultaneously both spectral information and 3D spatial information of polychromatic source objects in terms of a certain interferometry to measure 3D spatial coherence function. This paper shows the outline of that idea. An analysis of the depth resolution is also presented.
