Paper Abstract

The coherently emitted energy flux of thermal lamps is limited less to than 1 (mu) W and, therefore, is hardly useful in OCT. We describe a technique which enables the use of spatially incoherent light sources, like thermal light sources and transversal multi-mode lasers in the standard time-domain OCT technique. The beam power available for OCT depth scans is increased by combining several mutually incoherent OCT channels. This technique has advantages particularly in multiplex or parallel OCT: There is no coherent cross-talk between adjacent depth scans and the power available per pixel is not dependent on the number of parallel depth scans.
