METHOD FOR COMPENSATING THE ARTIFACTS GENERATED BY MOVING MEASUREMENT OBJECTS IN MEASUREMENT SIGNALS OF SWEPT-SOURCE OCT SYSTEMS

摘要

The present invention relates to a method for compensating the artifacts generated by moving measurement objects in measurement signals of swept-source OCT systems. According to the invention, the signal reconstruction is carried out only by specially adapted algorithms without the aid of additional reference signals with regard to the movement of the measurement object. Preferred developments and designs relate first to the specially adapted algorithms based on Fourier transform for processing the detected measurement signals. On the other hand, preferred developments and designs relate to the measurement signals to be detected, in particular to the measurement systems which are used for the generation thereof and which are based on optical coherence interferometry. Although the proposed method is intended in particular for use in ophthalmology, it can in principle be used wherever the signals reflected by curved surfaces or backscattered by structures are analyzed.
