Abstract
A technique is described for the fast recording of the information about both spatial and spectral details of an optical radiator. The recorded information is transformed into a spectral image that is easy to apprehend. The principle of spectral-image formation is based on the Fourier-transform relationship between the three-dimensional spatial coherence function of radiation and the radiator geometry, including its position-dependent spectral contents. Relations to other techniques are mentioned, and a result of a preliminary experiment is presented.
