Abstract
Optical device that comprises a spatial light modulator and a spectral filter that normally comprise several parts, such that each part of the filter (V; R; A; L) corresponds to at least one part of the modulator. The spectral filter is superimposed to the spatial light modulator such that the transmittance of each part of the filter is coordinated with the phase offset introduced by the corresponding part of the modulator. In one embodiment, the spatial light modulator is a programmable liquid-crystal device. The invention presents several ways in which to coordinate the transmittance of each part of the spectral filter with the programmed time variation of the phase offset introduced by each part of the spatial light modulator, such that each part of the latter receives light at a spectrally filtered wavelength and focuses it in the same plane.
