Abstract

Vorrichtung zum Verstellen der optischen Verzögerung in einem Strahlengang, insbesondere in einem Referenzstrahlengang eines OCT-Interferometers, mit einer wenigstens in einer ersten Schwenkebene um eine erste Schwenkachse schwenkbaren ersten Spiegeleinrichtung (10) zum wahlweisen Ablenken von Strahlen des Strahlenganges auf eine erste Verzögerungsstrecke aus einer Anzahl von ersten Verzögerungsstrecken mit unterschiedlichen optischen Verzögerungen, wobei die ersten Verzögerungsstrecken in wenigstens einem Verzögerungselement (16) ausgebildet sind, das zur Variation der optischen Verzögerung wenigstens eine in einer ersten Richtung gestufte erste Oberfläche (16.1) aufweist.Device for adjusting the optical delay in a beam path, in particular in a reference beam path of an OCT interferometer, with a first mirror device (10) pivotable about a first pivot axis at least in a first pivot plane for selectively deflecting beams of the beam path to a first delay path of a number of first delay lines with different optical delays, the first delay lines being formed in at least one delay element (16) which has at least one first surface (16.1) stepped in a first direction for varying the optical delay.
