Outline of Final Research Achievements

The purpose of this research is to realize two-dimensional real-time acoustic imaging by acoustic digital measurement.In order to realize the acoustic digital measurement, I studied on a method of improvement of the characteristics of the ultrasonic transceiver. However, the impulse response of the ultrasonic transceiver is not improved by the proposed method using negative feedback circuits and filters because the models of the proposed method is not practical. In addition to the research, we fabricated integrated circuits of low-pass filters to processes ultrasonic signals. As a result of measuring the characteristics of integrated circuits, the characteristics of the filters are different from the design because of the process variation of the integrated circuits. It is necessary to improve the degradation of the characteristics of filters caused by the process variations.
