Patent ID: 8159677

Claim:
An interferometric device specified by an observation range of an associated object under study, the observation range having a boundary, comprising: a source of low-coherence optical radiation having an operating wavelength, the low-coherence optical radiation specified by a coherence window; an optical interferometer optically coupled with the source of low-coherence optical radiation, the optical interferometer comprising at least one optical coupler, two arms, a first fiber-optic controlled scanner placed in one of the arms of the optical interferometer for performing a function of in-depth scanning of the coherence window of the low-coherence optical radiation within the observation range of the object under study, and a source of AC control voltage connected with the fiber-optic controlled scanner; and a delivering member for delivering low-coherence optical radiation to an associated object under study optically coupled with the source of low-coherence optical radiation and with the optical interferometer; wherein the optical interferometer further comprises a source of DC control voltage connected with the fiber-optic controlled scanner; and wherein the first fiber-optic controlled scanner further performs a function of controlling a boundary location of the observation range.
