Recovery of depth distributions of the backscattering efficiency in layered media using the detrending of OCT signals

The interpretation of OCT signals from layered strongly scattering media in the form of the sum of a diffuse and lowstep- scattered components is discussed. It is shown that when the latter component dominates over the diffuse contribution, the depth distribution of the backscattering efficiency can be recovered using the detrending of exponential attenuation of the OCT signal. The feasibility conditions for such detrending are discussed. Examples of experimental verification of this approach are presented.
