Arrangement for recording and measuring the distance of layers and structures

摘要

An interferometric measurement arrangement whose results are insensitive in first approximation to movements of the patient, it being possible to evaluate several points on the retina simultaneously, comprises an illumination device with light of small coherence length, an interferometric measurement arrangement with means for the measurable adjustment of the optical wavelength difference and an optical system for generating several partial illumination beams that are parallel to one another and are directed on to different regions of the retina, as well as a photoelectric receiver arrangement for each partial illumination beam.
