Abstract
In this summary, a new, fully akinetic FDML-like or so-called dual resonance sweeping regime for swept source optical coherence tomography, SS-OCT, at 1060 nm is demonstrated. A chirped fiber Bragg grating is used to provide sufficient dispersion in the laser cavity and a fiber intensity modulator is employed to modulate the optical field in the fiber cavity. A tuning range of 40 nm for sweep frequency of ≈1.7 MHz is obtained. Similarities in the operation of the dual resonance regime with a conventional dispersion tuned swept source and the FDML concept are included.
