    摘要: A method is disclosed for fixing at least one location in an examination field (9) with respect to a coordinate system (13). The method includes determining, in response to a request (65), coordinates of a first location (59) as a first coordinate set (x, y, z) allocated to the first location (59). A first recording and a second recording of topological data (69) in a spatially extended area around the first location (59) in the examination field (9) are obtained. The first and second recordings are compared to determine a displacement (&Dgr;x, &Dgr;y, &Dgr;z) of the first location (59) of the examination field (9) with respect to the coordinate system (13), the coordinates of the first coordinate set (x, y, z) allocated to the first location (59) are changed dependent upon the determined displacement (&Dgr;x, &Dgr;y, &Dgr;z) such that the changed coordinates substantially correspond to the coordinates of the first location (59) in the examination field (9) after the displacement thereof.

    摘要: A scanner for optical coherence tomography for linear scanning of an object with electromagnetic radiation, in which the scanning direction runs transversely of the direction of propagation of the electromagnetic radiation, includes a deflecting element rotatable around a rotation axis that deflects the electromagnetic radiation, incident along a direction of incidence, toward the object and, by its rotation, effects the linear scanning of the object. A beam forming optics is arranged on the object side of the rotatable deflecting element and concentrates electromagnetic radiation coming from the deflecting element. The rotation axis of the rotary deflecting element is parallel to the direction of incidence of the electromagnetic radiation.
