Simultaneous measurements of three-dimensional reflectivity distributions in scattering media based on optical frequency-domain reflectometry.

A new type of tomography system based on optical frequency-domain reflectometry is presented. Using an area sensor, the system can simultaneously measure three-dimensional reflectivity distributions in scattering media without the need for mechanical scanning. In preliminary experiments we demonstrate that a target (resolution chart) placed behind biological tissue can be imaged with high depth resolution (47 mu m) for a short measurement time.
