Abstract
An imaging system includes an illumination device for illuminating a target. A surgical microscope receives light from the target, the surgical microscope comprising at least one optical output port at which at least a portion of the received light is provided as an output from the surgical microscope. A tunable filter receives the portion of the received light provided as the output from the surgical microscope, the tunable filter being tunable to pass a filtered portion of the received light, the filtered portion of the received light having a plurality of wavelengths selected by the tunable filter and provided as output from the tunable filter. A high-resolution, broad-bandwidth electronic camera receives the light of a plurality of wavelengths selected by the tunable filter, the electronic camera converting the light of a plurality of wavelengths selected by the tunable filter to a plurality of electrical signals. A processor processes the plurality of electrical signals to form an image of the target.
