ABSTRACT:
A confocal spectral imaging system comprises a light source, a light modulator forming an illumination aperture and directing an illumination pattern to conjugate object locations, and analyzing means with a detection aperture, dispersive elements and a detector, wherein the illumination and detection apertures are in conjugate optical planes, and the light modulator consist of an array of light modulator elements, a group of which being arranged according to the illumination pattern and forming the illumination aperture, and are controlled such that the illumination pattern is directed to time-dependent changing conjugate locations of the object. A programmable light source comprises a white light source, dispersion means and a spatial light modulator with an array of individually time-dependent controllable modulator elements being illuminated with the dispersed light and providing a position selective transmittivity or reflectivity, so that a light with a predetermined wavelength distribution passes the light modulator.
