Abstract:
1. A method for measuring the properties of a target object, comprising: providing incident light comprising at least one spectral component having low coherence, wherein the incident light is to be illuminated on a target object in vivo; recording an intensity of one or more of at least one spectral component and at least one angular component of backscattering angle of backscattered light, wherein the backscattered light is to be backscattered from illumination of the incident light on the target object and wherein the backscattering angle is an angle between the direction of incident light propagation and the direction of backscattered light propagation; analyzing the intensity of the one or more of the at least one spectral component and the at least one backscattering angle of backscattered light to obtain one or more optical markers of the backscattered light, toward evaluating said properties; and adjusting a spatial coherence length of the incident light to select a depth of penetration of the target object by the incident light.
