摘要：
Systems and methods are described in this disclosure for an endoscopic optical system comprising a diffuse reflectance spectroscopy probe. The probe includes a light source and a plurality of photodetectors. Each photodetector is positioned at a difference distance from the light source such that an interrogation volume of each photodetector is based at least in part on the distance between the photodetector and the light source. In some implementations, each photodetector of the plurality of photodetectors is at least partially annular in shape and the photodetectors of the plurality of photodetectors are arranged concentrically.
