Assembly for carrying out an optical coherence tomography

An assembly comprising:

• first and second housings (9) (10);
• and
• an interferometer for carrying out an optical coherence tomography,
• wherein the interferometer is divided into two interferometer parts (1, 2) at
• a spatial distance from each other;
• wherein the two interferometer parts (1, 2) are movable relative to each other and are optically connected to each other by at least one flexible light guide (3, 4, 5) which bridges the spatial distance;
• wherein the first housing (9) comprises:
• the first interferometer part (1), comprising:
• electronic components;
• and
• a power supply unit (7);
• wherein the second housing (10) comprises:
• the second interferometer part (2), comprising:
• a camera head (8), comprising:
• a sample arm (11);
• a reference arm (12);
• and
• a plurality of single-mode fiber light guides leading to
• the sample arm (11) and to the reference arm (12);
• wherein the at least one flexible light guide comprises a flexible light guide designed as a polarization-maintaining light guide which consists of two polarization-maintaining light-guiding fibers (3a, 3b) connected to each other;
• wherein the respective crystal axes of which are arranged tilted by 90° relative to each other.
