Fourier-domain optical coherence tomography: next step in optical imaging

Wojtkowski M., Kowalczyk A., Targowski P., Gorczyńska I.

Vol. 32, nr 4

569-580

new implementation of Fourier domain optical coherence tomography (FDOCT) ś a method for imaging the in-depth structure of weakly absorbing and weakly scattering objects is demonstrated. By the reconstruction of both amplitude and phase it is possible to use negative and positive optical path differences to get images of objects of considerable thickness. This method eliminates parasitic autocorrelation terms inherently associated with FDOCT technique and improves the quality of images. The method, experimental set-up, data processing and applications for biomedical imaging are discussed and compared with the time domain version of optical coherence tomography
