Abstract
We study the influence of multiple backscattering on optical coherence tomography (OCT) images or pulsed-sounding images of layered turbid media. A method for calculating the signal of various orders of backscattering is proposed. The retarding effects of OCT-signal dropping are analyzed. The contrast attenuation of an image of a layered medium due to multiple backscattering is examined. The blurring effect of an image of the back boundary of a scattering layer, caused by a delay of multiply scattered photons compared with single-scattered ones, is studied theoretically and experimentally using an OCT device.
