Abstract

We demonstrate a new light source for OCT using a compact Nd:glass femtosecond laser spectrally broadened in a tapered single mode fiber. A reflective grating phase delay line permits high speed, broad bandwidth optical delay scanning. High speed and high resolution OCT imaging is achieved with 5 /spl mu/m axial resolution and 90 dB sensitivity. Axial scan speeds of 1 m/s are achieved, sufficient for real time imaging. This laser source is compact and is well suited for high resolution clinical imaging studies.
