Study on Local Strain Distribution Measurement for Structural Members by using Piezoelectric Material and Sensor Array
Local Strain Distribution Measurement Structural Members Piezoelectric Material Sensor Array
2009/4/30
A new technique for surface strain distribution measurement has been developed by the use of piezoelectric material and sensor array. A piezoelectric element (PVDF film) is mounted onto the structure ...
Improvement of FWM Conversion Efficiency by SBS-suppressed Highly Nonlinear Dispersion-Decreasing Fiber with a Strain Distribution
FWM Conversion Efficiency SBS-suppressed Nonlinear Dispersion-Decreasing Fiber
2015/7/31
We demonstrated 8dB SBS-suppression and a uniform dispersion simultaneously by down-sized dispersion-decreasing HNLF applying distributed strain. FWM wavelength conversion efficiency of -2dB was achie...
