Paper Abstract

A novel optical scheme for a full range Fourier domain optical coherence tomography (FD-OCT) is presented. This method avoids a mechanical scan for phase-shifting (mechanical M-scan) which enables a full range FD-OCT. A tilting reference wavefront is used to make variable phase offset of spectral interferometric fringes. Several spectral fringes are detected by a two dimensional CCD camera simultaneously. One axis of the CCD camera is occupied with the optical spectral axis, and the other axis is employed for phase offset variation. A few spectral fringes are extracted and used for phase-shifting algorithm. The principle of this system is confirmed with a plane mirror sample.
