Abstract

An Optical Coherence Tomography, OCT, device (100; 200; 410), in particular for an endoscopic measuring system (400), comprises at least one light source (110; 210); at least one cascaded interferometer arrangement (120, 140; 220, 240) having at least a first interferometer (120; 220) configured to receive light (L_S) emitted by the light source (110; 210) and at least a second interferometer (140; 240), the second interferometer (240) arranged behind the first interferometer (120) with respect to an optical path (L_S, L_IL, L_IM) of the OCT device (100; 200; 410); at least one image sensor (180; 280); and; at least one image fiber (160; 260) arranged between the cascaded interferometer arrangement (120, 140; 220, 240) and the image sensor (180; 280) with respect to the optical path (L_S, L_IL, L_IM) of the OCT device (100; 200; 410). The image fiber (160; 260) is configured to receive at least one interferometric image (L_IM) output by the second interferometer (140; 240) and to transmit the interferometric image (L_IM) towards the image sensor (180; 280) for detection of the interferometric image (L_IM) by means of the image sensor (180; 280).
