Apparatus and method for frequency domain optical coherence tomography

摘要

In an apparatus for frequency domain optical coherence tomography an optical frequency comb generator (113) is provided in a reference (220) or an object (240) light beam. The optical frequency comb generator transforms the spectrum of the light beam into a quasi-discrete spectrum. A spectral analyser (170) disperses the quasi-discrete spectrum on a multi-element detection device (174) such that each detection element (173) registers at most one of the quasi-discrete spectral components.
