Abstract:
1. A method for measuring the properties of a target object, comprising the steps of: recording an intensity of one or more of at least one spectral component and at least one angular component of backscattered light, wherein the backscattered light is to be backscattered from the illumination of incident light on a target object; selecting a depth of penetration of the target object by the incident light via adjusting a spatial coherence length of the incident light, wherein the depth of penetration is to be determined as based upon characteristics of the target object; and further recording an intensity of at least one azimuth angle of the one or more of at least one spectral component and the at least one angular component of the backscattered light, wherein the angular component of the backscattered light is an angle between the backscattered light propagation direction and the incident light propagation direction, and the azimuth angle is an angle between the incident light polarization and the projection of the direction of the incident light onto a plane in which an electric field of the incident light oscillates.
