Abstract

A method for recording and reconstructing spectral and spatial intensity distributions of sources is described. Three-dimensional information (two for spatial and one for wavelength) of the sources is simultaneously recorded as their projected forms by an imaging system including a crossed phase grating. A modified multiplicative algebraic technique is developed to reconstruct the original distribution. In experiments we obtained nine projection patterns with equal brightness of a color slide illuminated by a tungsten lamp. The reconstructed distribution shows good agreement with that measured by interference filters.
