DEVICE FOR LOW-COHERENCE ENHANCED BACKSCATTERING SPECTROSCOPY

摘要

PROBLEM TO BE SOLVED: To provide a device for low-coherence enhanced backscattering spectroscopy.SOLUTION: A device includes a probe that emits partially-coherent incident light obtained from a light source on an object and receives interacting light scattered backward. The probe includes: a supply channel that has at least one light-distributing optical fiber having a distal end part connectable to the light source and having a proximal end part adapted so as to distribute the incident light to be emitted on the object; a light collection channel that has at least one light-collecting optical fiber having a proximal end part for receiving the light scattered backward from the partially-coherent light emitted on the object and having a distal end part formed so as to be connected to a light-receiving end; and an optical component that is optically connected to one or more proximal end parts of the light-distributing optical fiber and the light-receiving optical fiber and is operable so as to select spatial coherence length of the incident light.
