Optimized device for the swept source optical coherence domain reflectometry and tomography

摘要

In the case of the coherence - optical device is light with the aid of an interferometer for distance measurement and imaging of reflecting and scattering surfaces of the human eye is used.According to the invention, the optimized device consists of a, on the desired measuring range z_Oct tuned, tunable light source having a resonator length l_R, an interferometric measuring arrangement, a data producing unit for detecting the light scattered back from the sample and a data processing unit. In this case, the resonator length l_R the tunable light source, not only to the desired measuring range z_Oct, but also on the entire interferometric measuring arrangement, so that in the interferometric measuring system existing defects no interference signals in the desired measuring range z_Oct to generate.The present invention relates to a device for ss ocdr and ss oct and, in particular in ophthalmology for very eyes scan on the human eye provided. In principle, the device, however, also be used on other technical fields, in which distances with a high degree of precision, are to be measured interferometrically.
