2016 JOINT IEEE INTERNATIONAL SYMPOSIUM ON THE APPLICATIONS OF FERROELECTRICS, EUROPEAN CONFERENCE ON APPLICATION OF POLAR DIELECTRICS, AND PIEZOELECTRIC FORCE MICROSCOPY WORKSHOP (ISAF/ECAPD/PFM) 2016年 [査読有り]
A new non-destructive evaluation technique for surface mounted capacitor (SMC) based on photothermal frequency modulation is proposed. The slight change of capacitance by a thermal wave makes an oscillation frequency modulate, enabling detection b...
A new differential cavity ring-down spectroscopy (CRDS) detection technique is proposed. This technique features the wavelength differential detection by alternating two side bands generated by an optical single side band modulator. This is useful...
