1. A robotic surgical system comprising: an endoscope held by and positioned by a robotic manipulator arm of the robotic surgical system; a visible imaging system coupled to the endoscope, wherein the visible imaging system captures a visible image of tissue; an alternate imaging system coupled to the endoscope, the alternate imaging system comprising: a capture unit configured to capture a first fluorescence image of at least a portion of the tissue, and a device coupled to the capture unit, the device configured to use information associated with the first fluorescence image to generate a second fluorescence image in a stereoscopic pair of fluorescence images; and a stereoscopic video display system coupled to the visible imaging system and to the alternate imaging system, wherein the stereoscopic video display system outputs a real-time stereoscopic image comprising a blend of another fluorescence image associated with the captured fluorescence image, the second fluorescence image and the visible image.
