Abstract
Systems, methods, and apparatuses of elastic light scattering spectroscopy and low-coherence enhanced backscattering spectroscopy are described here. An apparatus couple-able to a light source and a target object, to facilitate light transmission between the light source and the target object, the apparatus comprises: a probe to emit incident light that is partially coherent obtained from the light source onto the target object and to receive interacted light, the interacted light to be backscattered light from illumination of the incident light on the target object, the probe comprising: a delivery channel having at least one delivery optical fiber with a distal end portion couple-able to the light source and a proximal end portion suited to couple the incident light to the target object, a collection channel having a first collection optical fiber suited to collect substantially co-polarized backscattered light and a second collection optical fiber suited to collect substantially cross-polarized backscattered light.
