Frequency Measurement of Dynamic Stress in Polarization Maintaining Fibers
Pubblicazione 2018-01-01TestoUp to now, the distributed polarization coupling (DPC) measurement system based on white light interferometry (WLI) has been mainly studied for static and quasi-static measurement. In this paper, we developed the DPC system to measure the instantaneous frequency of dynamic stress. First, we set up a...

Automatic Interference Term Retrieval From Spectral Domain Low-Coherence Interferometry Using the EEMD-EMD-Based Method
Pubblicazione 2016-01-01TestoLow-coherence interferometry (LCI) has proved to be a useful tool in optical measurement and detection. However, the noise that is present in practical applications makes interference term retrieval (ITR) difficult. In this paper, we propose a novel technique based on ensemble empirical mode decompo...

A New Method for Determining the Sampling Volume and the Number of Particles Within It for Particle Concentration Identification in Defocused Interferometric Particle Imaging
Pubblicazione 2017-01-01TestoInterferometric particle imaging (IPI) is a robust technique for measuring particle size and velocity. In defocused IPI that is uniquely valuable to quality control of a spray field, a reliable method for identifying the particle concentration in the volume sampled by the sheet beam remains outstand...

Method Based on Fast Fourier Transform for Calculating Conical Refraction of Beams With Noncircular Symmetry
Pubblicazione 2017-01-01TestoConical refraction of optical beams with circular symmetry is often analyzed using Belsky–Khapalyuk–Berry (BKB) theory; however, for beams with noncircular symmetry, it is difficult to obtain analytical expressions for far-field diffraction patterns. We propose a method, based...

Spatial Resolution Enhancement Based on Peak Splitting in Low-Coherence Interferometry Signal
Pubblicazione 2016-01-01TestoLow-coherence interferometry (LCI) has been a useful tool to detect distributed polarization coupling (DPC) points in polarization-maintaining fiber (PMF). However, due to birefringence dispersion, two close coupling points in long PMF are usually difficult to be distinguished. A novel method in our...
