This paper presents a new method of digital holographic three-dimensional imaging spectrometry. The method is based on the measurement of new type of volume interferogram, called Rotated-Hyperbolic-type volume interferogram, obtained with the existing interferometer. We report the first demonstration of the method in which a monochromatic point source is used as the measured object. The results include 3-D spatial information and spectral information of a monochromatic point source. This experimental result corresponds to the impulse response function defined over a four dimensional (x, y, z, k) space. As a result, the method is confirmed to have the superior imaging characteristics in the z direction.
