Paper Abstract

Optical coherence tomography (OCT) is the novel method for producing three-dimensional images of the relatively thin (up to 2 mm) layers of the biological tissues. OCT is based on the interferometry of low-coherence light. The important factors, characterizing OCT, are the measurement speed and the quality of the obtained images. Both of these two factors actually characterize the amount of new information generated during the measurement with OCT. Using the Shannon's information theory; the quantitative characteristics of the information efficiency of OCT are introduced. Information capacities of OCT realizations based on scanning low-coherence interferometry and on spectral interferometry are defined and compared. It is shown that, image quality being the same, information capacity of spectral interferometry exceeds that of scanning low-coherence interferometry by a factor equal to the number of resolvable elements in a single in-depth scan. The speed of measurement and the image quality characterizing two methods are also compared.
