论文摘要
在多个动态的行业（例如结构性健康监测，无线能量收集设备，测量血流等）中，在多种动态行业中的应用中，PEREZOElectric材料（例如锆甲酸二氧化甲酸酯（ZRXTI1-X）O3（PZT）的应用都在增加。该论文的主要目的是通过双重点上的点兴奋和检测方法来降低图像，以降低点的损害和检测方法。尽管如此，这些转换方案可以扩展到其他嘈杂的图像。为了有效地研究，PZT陶瓷中的地下缺陷及其图像中已经检查了降解方案，并提出了量子定量的度量，提出了以前不存在的噪声。 Delta脉冲用于激发PZT陶瓷中的声波。消除了计算噪声能量的指标辅助工具，并验证了DeNoising技术的熟练程度。
The application of piezoelectric materials, such as Lead Zirconate Titanate (ZrxTi1-x) O3 (PZT) is increasing in multiple dynamic industries such as structural health monitoring, wireless energy harvesting devices, measuring blood flow, etc.The main aim of this paper is to denoise the images generated by dual point excitation and detection method for subsurface damage detection. Nonetheless, these denoising schemes can be extended for other noisy images. In order to study effectively, the subsurface defects in a PZT ceramics and from its images the denoising schemes have been examined and a metric for the quantification of the noise is proposed which was previously non-existent. A delta pulse is used for excitation of the acoustic waves in PZT ceramics. The metric aids in calculating the energy of the noise been removed and also to verify the proficiency of the denoising technique been incorporated.
