Abstract
The invention relates to an interferometer for optical tomography, comprising a sample arm configured to direct a sample beam to and receive a reflected sample beam from a sample structure, in particular an eye,and a reference arm comprising at least one reference mirror and configured to direct a reference beam to and receive a reflected reference beam from the at least one reference mirror. All optical elements of the reference arm are arranged in a fixed positional relationship with respect to each other, and the optical elements of the reference arm comprise an adjustable optical element having an adjustable focal length. The interferometer of the invention allows a fast reference plane selection in optical coherence tomography by using a fast dynamic confocal system.
