Abstract

An apparatus for optical swept source coherence tomography comprises a spectrally tuneable source for emitting coherent light and a detector for acquiring the intensity of remitted light backscattered from an object irradiated with the coherent light of the source. Further the apparatus comprises a control device which is set up to control the light source and the detector in such a way that the detector performs intensity acquisitions in accordance with a defined number of measurements while the light source is tuned the control device further being set up for the purpose of altering the measurement depth or/and the axial resolution of the tomography to alter the defined number of measurements or/and a spectral measurement bandwidth within which the detector performs the intensity acquisitions.
