Abstract

A scanning delay line, an apparatus for optical coherence tomography (OCT) and a method of scanning an optical path difference. A scanning delay line for an interferometer comprising an input aperture and an output aperture different from said input aperture, a dispersive element 2, an optical element 3 and a controllable tilt mirror 4. The scanning delay line is configured to let the incident light traverse the dispersive element twice, traverse the optical element four times and be reflected twice from the tilt mirror. The tilting of the tilt mirror results in scanning of the optical path. The scanning delay line can have additional mirrors for redirection of the light. The apparatus incorporates the scanning delay line.
