Multi spectral three-dimensional imaging by hyperbolic-holography using single detector

Abstract

We present a method to obtain a set of spectral component of three-dimensional images based on measurements of hyperbolic volume interferogram. The method uses an improved two-wavefront folding interferometer incorporating with a single detector of high sensitivity. The method may apply to usual polychromatic objects because it is kind of incoherent holography combined with Fourier transform spectroscopy. First experimental result of the method is shown to demonstrate the capability to acquire continues spectral profile of three-dimensional polychromatic object.
