Length and refractive index measurement by Fourier transform interferometry and frequency comb spectroscopy

Original language description

In this paper we describe a progress we have made in our simultaneous length measurement and the femtosecond comb interferometric spectroscopy in a conventional arrangement with a moving mirror. Scanning and detection over an interval longer than the distance between two consecutive pulses of the frequency comb allow for a spectral resolution of the individual frequency modes of the comb. Precise knowledge of the comb mode frequency leads to a precise estimation of the spectral characteristics of inspected phenomena. Using the pulse train of the frequency comb allows for measurement with highly unbalanced lengths of interferometer arms i.e. an absolute long distance measurement. Further, we present a non-contact (double sided) method of measurement ofthe length / thickness of plan-parallel objects (gauge blocks, glass samples) by combining the fs comb (?white light?) with single frequency laser interferometry. The position of a fringe packet is evaluated by estimating the stationary p
