METHOD AND DEVICE FOR THE SEQUENTIAL RECORDING OF INTERFEROMETRIC DEEP SECTIONAL IMAGES AT DIFFERENT DEPTHS, IN PARTICULAR FOR ANALYSIS OF THE EYE

摘要

The invention relates to a method for the sequential recording of interferometric sectional images at different depths, in particular for analysis of an eye, wherein, by means of an interferometer (1) that contains an optical reference path (9) and an optical sample path (10), a sample beam (14) sweeps across a measurement area (3) of a sample (2), in particular of the eye, in order to generate a deep sectional image. The invention further relates to a device for carrying out the method. The object is to develop the method and the device in such a way that the optical and geometric paths in a sample arm and/or reference arm of the interferometer can be switched quickly between two or more positions. To achieve this object, it is proposed that the path length of the sample beam (14) and/or of the reference beam (15) is changed by means of a path length switching unit (16), and deep sectional images are generated at at least two different depths of the sample (2), and the change of path length takes place in a switching unit by deflection of the beam paths to different geometric paths.
