Abstract

An apparatus, including: an electromagnetic radiation source producing radiation for illuminating a sample located at an optical path depth, the electromagnetic radiation source providing the radiation to the sample to facilitate determining the optical path depth within the sample; an interferometer including: a reference arm to which a first portion of the radiation is delivered, a sample arm to which a second portion of the radiation is delivered, a first optical subsystem coupled to the sample arm to interrogate the sample with the radiation delivered to the sample arm and to collect backscattered radiation from the sample, and a second optical subsystem coupled to the reference arm and the first optical subsystem to generate interference fringes between the collected backscattered radiation and the radiation delivered to the reference arm; and a data collection and processing system in communication with the interferometer configured to compute the optical path depth of the sample from the received interference fringes.
