Signal detection algorithms for interferometric sensors with harmonic phase modulation: miscalibration of modulation parameters
Leonid Liokumovich, Konstantin Muravyov, Philipp Skliarov +1
In the current paper, we have developed an analytical apparatus, allowing to calculate the phase error, produced by miscalibration of modulation parameters. The case of harmonic mo…
Signal detection algorithms for interferometric sensors with harmonic phase modulation: distortion analysis and suppression
Leonid Liokumovich, Andrei Medvedev, Konstantin Muravyov +2
In current paper, distortions in digital demodulation schemes with harmonic phase modulation for interferometric optical sensors are considered. In particular, the influence of tar…
Measurement of dynamic interferometer baseline perturbations by means of wavelength-scanning interferometry
Nikolai Ushakov, Leonid Liokumovich
A novel approach for measuring fast oscillations of an absolute value of interferometer optical path difference (OPD) has been developed. The principles of frequency-scanning inter…
