Apparatus and method for frequency domain optical coherence tomography

In an apparatus for frequency domain optical coherence tomography an optical frequency comb generator (113) is provided in the combined light beam (250) formed from a reference light beam (220) and an object light beam (240). The optical frequency bomb generator transforms the spectrum of the combin...

More Information
Summary:In an apparatus for frequency domain optical coherence tomography an optical frequency comb generator (113) is provided in the combined light beam (250) formed from a reference light beam (220) and an object light beam (240). The optical frequency bomb generator transforms the spectrum of the combined light beam (250) 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.
