Abstract:
A confocal spectral imaging system comprising:light source means;light modulator means being arranged in a light path between said light source means and an object under investigation, said light modulator means comprising a two-dimensional array of light modulator elements, a group of which being arranged according to a predetermined illumination pattern to be formed in conjugate locations of said object, said light modulator elements forming an illumination aperture, wherein said light modulator means is controllable such that the illumination pattern is directed to time-dependent changing conjugate locations of the object, andanalyzing means with spectrally dispersive elements and a detector camera, said analyzing means capable of collecting from said object spectrally resolved light with multiple wavelengths in a dispersed state, wherein a detection aperture is arranged in a light path between said object and said spectrally dispersive elements, and said illumination and detection apertures are placed in conjugate optical planes.
