Abstract:
1. An SS-OCT interferometer apparatus for measuring a sample or an eye, the apparatus comprising: a measurement radiation source emitting measurement radiation that is adapted to interferometrically generate a measurement signal and to generate a depth-resolved contrast signal of the sample from the measurement signal by spectral tuning of a central wavelength of the measurement radiation; a control device; a sample-motion detector that provides a motion signal to the control device, the motion signal indicating movement of the sample or movement within the sample in the form of sample correction radiation; wherein before or during the generation of the depth-resolved contrast signal, the control device corrects the measurement signal with relation to measurement errors that are caused by movements of the sample or movements within the sample that occurred during the tuning of the central wavelength by utilizing the motion signal wherein the apparatus further comprises:
