In vivo optical coherence tomography in ophthalmology

If the more or less conventional interferometric techniques are applied in vivo, movements of the subject might falsify the measurement. This led us to develop the dual beam interferometry technique which compensates for these movements. First in vivo tomographic images of the human eye are presented. The implications of the application of partial coherence techniques in dispersive media are discussed. Synthesizing tomograms from interfero- metrically obtained scans is rather time-consuming and therefore difficult to apply in vivo. Hence we discuss the application of spectral interferometry to optical coherence tomography. The spectral interferometry technique does not need moving components.
