Abstract:
A fiber-based polarization sensitive optical coherence tomography (PS-OCT) system uses a new polarization diversity detection (PDD) scheme and requires no active polarization modulating components. Retardation of the sample can be determined from amplitudes of arbitrarily-oriented x- and y-components of the reflected light. A hybrid custom 50/50 coupler with single-mode fiber inputs and polarization maintaining (PM) fiber outputs combines light from sample and reference arms of an interferometer. Another embodiment provides a system adapted to provide co-registered autofluorescence-optical coherence tomography (AF-OCT) imaging. AF excitation light is introduced and collected AF light is extracted at a fiber optic rotary joint (FORJ) equipped with an embedded dichroic mirror. A probe tip that uses a clad fiber to supply light to a focusing element provides enhanced OCT and AF performance.

Die Fasern (16) sind dabei in einem ersten Träger (14) geführt, der eine Koppelfläche (22) aufweist, an der ein erster planarer Lichtwellenleiterchip angekoppelt ist, der ins- besondere als Combiner (18) ausgebildet ist.
Abstract:
An optical rotating joint installation; comprising: a drive shaft for a rotating interface, the drive shaft comprising a hollow central bore; and an optical rotating joint located in the hollow central bore. The proportion of the cross-sectional area of the material retained in the annular section of the drive shaft is preferably greater than or equal to 50%, more preferably 60%, yet more preferably 75%. The diameter of the hollow central bore is preferably less than or equal to 20mm, more preferably 16mm. The optical rotating joint installation may be provided as a retro-fit to replace an existing solid drive shaft that does not have an optical rotating joint, for example by hollowing out the existing solid drive shaft or by replacing the existing solid drive shaft with a drive shaft with a hollow central bore.
