A) Schematic of prototype instrument. Separate standard definition detectors are used to collect either B) white light (WL) or C) fluorescence images. A filter located in between the fluorescence objective and detector passes light from FITC. D) Reflectance images collected with the same detector are co-registered with fluorescence. E) Summary of optical parameters. White light and fluorescence/reflectance images are collected at 20 and 10 frames/sec, respectively. aw – air/water nozzle.
