| Research Abstract |
1.We proposed a new one-dimensional model to analyze a photoacoustic (PA) signal of optically opaque materials measured by a polyvinylidene difluoride (PVDF) sensor. In order to check the validity of the proposed model, we measured the inclination of the frequency dependence of the signal measured by the PVDF and compared it with a theoretical value. The obtained inclinations were comparable with the simulated inclinations in the cases of the film thickness of the PVDF.
2.We proposed a new method "reformed method of simultaneous measurement of multiple frequencies (RSMMF method)" in order to improve the signal-to-noise-ratio (SNR) in high frequency components of the PA signals. Moreover, the time for data treatment of a frequency dependence of the PA signal amplitude measured by this method could be reduced by 1/5 compared with that in a convebtional method using a lock-in amplifier.
