Paper Abstract

We describe an improved setup for differential phase contrast OCT. Phase differences between transversally adjacent beams are derived from the phase functions of the interferometric signals. The accuracy of the system is demonstrated by imaging pure phase objects consisting of chromium layers containing steps of approximately 100 - 200 nm height. By imaging through a scattering layer of 3 mean free path thickness (single pass), phase imaging is still possible with phase noise of only +/- 2 degrees.
