Abstract
Devices, arrangements and apparatus adapted to propagate at least one electro-magnetic radiation are provided. In particular, a probe housing, a sample arm section and a reference arm section can be included. For example, the sample arm section can be at least partially situated within the probe housing, and configured to propagate a first portion of the electro-magnetic radiation that is intended to be forwarded to a sample. The reference arm section can be at least partially situated within the probe housing, and configured to propagate a second portion of the electro-magnetic radiation that is intended to be forwarded to a reference. In addition or as an alternative, an interferometer may be situated within the probe housing. The first and second portions may travel along substantially the same paths, and the electro-magnetic radiation can be generated by a narrowband light source that has a tunable center wavelength. Further, the first and second portions may be at least partially transmitted via at least one optical fiber. A splitting arrangement may be provided which splits the electro-magnetic radiation into the first and second portions, and positioned closer to the sample than to the source of the electro-magnetic radiation, and the first and second portions may be adapted to propagate in different directions. An apparatus may be provided that is configured to control an optical path length of the second portion.
