DEVICE FOR SWEPT SOURCE OPTICAL COHERENCE DOMAIN REFLECTOMETRY

摘要

A device for swept-source optical coherence domain reflectometry (SS OCDR) on moveable samples, particularly human eyes, for obtaining A-scans, having a measuring range according to the sample length and having a laser light source which can be adjusted by a main wave number k0 and at least one receiver for the light dissipated from the sample, wherein the sample is illuminated on the sample surface by a measurement beam having a diameter D by way of a coupling device. The light source has a spectral line width of δk<168 m−1 and the adjustment of the light source is carried out in τ<44 s/(D*k0).

1. A device for swept source optical coherence domain reflectometry (SS OCDR) on a movable sample, for the purpose of obtaining A-scans, having a measuring range corresponding to a sample size, comprising:
a tunable laser light source; at least one receiver for light backscattered from the sample, wherein the sample is illuminated on the sample surface with a measurement beam of diameter D; wherein the light source has a line width of δk<168 m−1, and further wherein tuning of the light source is performed in τ<44 sec/(D*k0) about a centroid wave number k0.
