Interferometric Three-Dimensional Imaging Based on Retrieval of Generalized Radiance Distribution

GENERAL AND PHYSICAL OPTICS

Abstract

A new three-dimensional (3-D) imaging technique is proposed. The images are obtained as spatial distributions of Walther’s first and second definitions of the generalized radiance function. The generalized radiance function can be retrieved from the cross-spectral density measured across an observation plane using a propagation law described in the Fourier domain. The longitudinal resolution of the second generalized radiance function is much higher than that of the first definition, so that the second generalized radiance function is thus useful for the 3-D imaging. Full mathematical descriptions of the principle are given. Results of experimental demonstrations conducted by incorporating uncorrelated two point sources are also reported.
