Imaging system

摘要

Imaging systems are provided allowing examination of different object regions spaced apart in a depth direction by visual microscopy and by optical coherence tomography. An axial field of view and a lateral resolution is varied depending on which object region is examined by the imaging system. The proposed imaging systems are in particular applicable for thorough examination of the human eye.

1. A system comprising an OCT system, the OCT system comprising:
an interferometer providing a measuring arm extending towards an object to be measured, a reference arm, and including an OCT measuring light source, at least one beam splitter and a detection system configured to detect OCT measuring light returned from the measuring arm and superimposed with OCT measuring light returned from the reference arm, wherein the OCT system is switchable to a first operation mode and a second operation mode; wherein in the first operation mode, a spectral width of the OCT measuring light, emitted from the OCT measuring light source, is smaller or at least two times smaller than in the second operation mode; and wherein in the second operation mode, a lateral width of a beam waist of a beam of the OCT measuring light is smaller or at least two times smaller than in the first operation mode.
