项目摘要

The aim of this research is to establish the system to image simultaneously multi-information at the same space of the object by the multi-functional piezoelectric elements. In this study, we tried to establish two types of imaging systems-linear array and cylindrical types-by multifunctional piezoelectric elements, and we achieved some positive results.In linear array typed imaging system for the living body, we tried to establish the electrical and ultrasonic simultaneous measurement system using eight piezoelectric elements. The imaging system is constructed by the analog switches, the I/O board and the 8-channel simultaneous AD board. In the experiment, electrical and ultrasonic properties of the agar as the living body model were measured by the imaging system. From results, we suggested that it is possible to measure the electrical and ultrasonic properties by using the proposed system, although there are some problems should be solved in the measurement accuracy and measurement algorithm.In cylindrical imaging system for industrial pipeline, we tried to establish the imaging system using sixteen piezoelectric elements. We established the imaging system constructed by the switching system, the I/O board, and the 2-channel simultaneous AD board. In the experiment, detection of acrylic column or acrylic pipe of thin film in the distilled water was demonstrated. From results, we suggested that simultaneous imaging of electrical and ultrasonic properties is possible.To assess the possibility of the multi-information imaging using multifunctional piezoelectric elements, three parameters of a target in the homogeneous medium were detected from electrical and ultrasonic properties measured by a pair of piezoelectric elements. As results, we presented that detection of three parameters of the object is possible by the proposed method. Therefore, we suggested the possibility of multi-information imaging using multifunctional piezoelectric elements.

本研究的目的是利用多功能压电元件，建立一个在物体同一空间同时成像多种信息的系统。在本研究中，我们尝试了用多功能压电元件建立两种类型的成像系统--线阵和圆柱型，并取得了一些积极的成果。在线阵型活体成像系统中，我们尝试了用8个压电元件建立电和超声同时测量系统。成像系统由模拟开关、I/O板和8通道同步AD板组成。在实验中，作为活体模型的琼脂的电学和超声特性由成像系统测量。实验结果表明，该系统可以用于管道的电特性和超声特性的测量，但在测量精度和测量算法上还存在一些问题。在工业管道圆柱形成像系统中，我们尝试建立了十六个压电元件的成像系统。我们建立了由交换系统、I/O板和双通道同步AD板构成的成像系统。在实验中，演示了在蒸馏水中检测薄膜的丙烯酸柱或丙烯酸管。为了验证多功能压电元件实现多信息成像的可能性，利用一对压电元件测量均匀介质中目标的电特性和超声特性，检测目标的三个参数。作为结果，我们提出的检测的三个参数的对象是可能的，所提出的方法。因此，我们提出了使用多功能压电元件进行多信息成像的可能性。
