摘要

A time domain optical coherence tomography (OCT) system without moving parts is described, which isnbased on multiheterodyning utilizing two mode-locked femtosecond lasers. By synchronizing the two lasersnto slightly different repetition rates and coupling to an interferometric OCT setup, we obtain amplitude-nmodulated beat signals representing the structure of the specimen under investigation. Our system is suit-nable for biological imaging as well as technical applications. We demonstrate high axial imaging depths ofn150 mm with up to 5000 axial scans per second, achieving equivalent path scanning velocities of 750 m/s.n© 2008 Optical Society of American.
