The present invention relates to an optical coherence tomography method, comprising: providing a beam of imaging radiation from a radiation source of an optical coherence tomography apparatus; directing, using directing optics, the beam of imaging radiation towards a fundus of a human or animal eye; and receiving a reflected portion of the imaging radiation by the optical coherence tomography apparatus; wherein the method further comprises: providing, by a tracking camera, a tracking image of an image area covering at least a part of said fundus; analyzing the tracking image for detecting a displacement of the fundus; and adapting, at least dependent on the detected displacement, a direction of the beam of imaging radiation by actuating an optical correction unit of said direction optics; and in addition to said adapting of the direction of the beam of imaging radiation, adapting a location of the image area on said fundus imaged by the tracking camera at least dependent on the detected displacement.

Optical coherence tomography method, system and computer program product therefor

An optical coherence tomography microscopy apparatus () is presented for detecting a three-dimensional image of an optically translucent or reflective sample object (OS), the apparatus comprising an interferometric optical setup including a photo sensor unit (). A sense signal Si from the photo sensor unit () is detected using a detection reference signal. The detection reference signal is derived from a signal indicative for a relative displacement of the sample object (OS) with respect to a reference object.
