A method and apparatus is disclosed for multi-mode spectral imaging. In one embodiment, the present invention comprises the steps of illuminating an object with a modified illumination profile, producing a reflected, transmitted or fluorescence image of the illuminated object, scanning the object, and re-imaging the reflected, transmitted or fluorescence light after modifying the light's optical state. The present invention preferably works in conjunction with other imaging systems to provide both high-spectral resolution images with lower temporal resolution and multiple image acquisition with high temporal resolution.

L'invention porte sur un procédé et un appareil d'imagerie spectrale multimode. Dans une exécution, l'invention comporte les étapes suivantes: éclairage d'un objet par un profil d'éclairage modifié; production d'une image réfléchie, émise ou fluorescente de l'objet éclairé; balayage de l'objet; et nouvelle production de la lumière réfléchie, émise ou fluorescente après avoir modifié l'état optique de la lumière. L'invention fonctionne de préférence en association avec d'autres systèmes d'imagerie pour fournir à la fois des images à résolution spectrale élevée et faible résolution temporelle et permettre l'acquisition d'images multiples de résolution temporelle élevée.
