Abstract: An optical device modulates radiation such as light from an extended object and focuses it onto a single detector in such a way that the modulation gives both spatial resolution of different points on the object and spectral resolution of light coming from each point on the object. The signal received by the detector can then be demodulated to reconstruct both the spatial and spectral properties of the initial extended object. A mask pattern is used, which can be variably exposed in successive steps to produce a cyclic encoding pattern in two dimensions. For an image resolved into p X m elements, the mask need only have (2p-1) (2m-1) elements, instead of p2 X m2 modulating elements.
