Abstract

Tomography deals with the generation of slice images of the internal structure of three-dimensional objects. Usually this is a two-step process consisting of data acquisition followed by image generation. Depending on the radiation used data are acquired by either transmitted or reflected radiation. Presently, in optical coherence tomography (OCT) the reflected straight ray approach is used and the object is scanned by laterally displacing the incident beam across the region of interest. At each beam position depth information is obtained by low coherence interferometry (LCI). Both LCI and OCT have found important applications in medicine, at the moment mainly in ophthalmology.
