Publication number: 20220244178Abstract: The invention relates to a method for controlling a semiconductor-laser-diode-based SS-interferometer system (SS=swept source), which allows for a wide range of application and is suitable for use in ophthalmology, in particular for imaging and for determining biometric measurement values of the eye. In the method according to the invention, by means of periodic current modulation, the operation of single semiconductor laser diodes is designed such that a highly coherent spectral laser line can be adjusted with a highest possible repetition rate and over a wide wavelength range. In addition, the following parameters: centre wavelength, sweep rate, sweep range, optical power in the eye and coherence length are adjusted such that the method is suitable for imaging and biometric applications via whole-eye scans. The proposed semiconductor-laser-diode-based SS-interferometer system is provided, in particular, for biometric measuring of the eye.Type: ApplicationFiled: February 28, 2020Publication date: August 4, 2022Applicant: Carl Zeiss Meditec AGInventors: Rainer LEITGEB, Manfred DICK, Roland BERGNER, Ralf EBERSBACH, Thomas PABST

Patent number: 9155462Abstract: A short coherence interferometer for measuring several axially spaced-apart regions of a sample, especially of an eye, which has a measuring optical path, through which the measuring radiation falls on the sample, a tunable interferometer for the axial, relative retardation of parts of the radiation, wherein the axial relative retardation is assigned to the axial spacing of the regions and a detector for producing an interference signal from interfering measurement radiation, scattered or reflected back from the sample as sample radiation. The tunable interferometer divides the sample radiation into two parts, which are axially relatively retarded and superimposed so as to interfere. During the superimposition, the tunable interferometer forms individual radiations, which represent quadrature components of the sample radiation, and the detector detects the individual radiations.Type: GrantFiled: June 12, 2009Date of Patent: October 13, 2015Assignee: Carl Zeiss Meditec AGInventors: Martin Hacker, Ralf Ebersbach, Thomas Pabst
