Abstract (en)
[origin: EP2626471A2] The method involves directing the measuring beam (2'') emitted by a radiation source (1) onto the sample (5) and directing the reference beam (2') onto a reference sample (4). The spectral interference of both beams after reflected on the samples or after passing the samples is recorded by a spectrograph (6). The interferogram is numerically derived with respect to the angular frequency. The zero crossovers for preset received function are calculated and the frequency-dependent group delay is calculated from the zero crossovers according to the predetermined equation. An independent claim is included for device for optical inspection of sample using spectral interferometry.
