In view of the problem of specifying a device for performing optical coherence tomography which is capable of reliably detecting the dimensions of an object or of structures of an object during an image capture of said object or of said structures and which has a structure that is as simple as possible, a device (10) for performing optical coherence tomography, comprising an interferometer with a light source (1), a reference arm (4) and a sample arm (5), wherein the light transmitted by the light source (1) can be split by a beam splitter (6a) such that first light is able to be guided on the reference arm (4) and second light is able to be guided on the sample arm (5), wherein the first light and the second light are able to be brought into interference and wherein a detection apparatus (3) for detecting and processing signals of the interfering first light and second light is arranged, is characterized in that an optical element (2) is arranged and is capable of further splitting the first light in the reference arm (4) into primary light (I) and secondary light (II), wherein the primary light (I) is able to be guided on a first light path (4a) and wherein the secondary light (II) is able to be guided on a second light path (4b), the length of which differs from that of the first light path (4a).
An apparatus for performing optical coherence tomography, comprising an interferometer having a light source, a reference arm, and a sample arm, wherein the light emitted by the light source may be split using a beam splitter such that first light may be guided along the reference arm and second light may be guided along the sample arm, wherein the first and the second light may be made to interfere and wherein a detection device is arranged for detecting and processing signals of the interfering first and second light, characterized in that an optical element with which the first light in the reference arm may be split further into primary light (I) and secondary light (II) is arranged, wherein the primary light (I) may be guided along a first light path and wherein the secondary light (II) may be guided along a second light path, the length of which differs from that of the first light path
