Abstract [eng] |
The aim of this work is to design and investigate a portable ultrasound system adapted for spectroscopy research. The work presents the principles of ultrasonic spectroscopy, overviews the application areas. The analysis of the commercially available ultrasonic systems was carried out. It was shown that the systems offered on the market are not portable, do not support wireless data transmission. Commercial systems are high cost, because of the high flexibility and excessive amount of controlled parameters. Requirements for the new system design have been rectified. The structure of the system has been designed. The system consists of three main subsystems: i) excitation; ii) receiving and digitizing, and iii) control, synchronization and communication. The aforementioned subsystems have been designed and manufactured as separate devices, in order to quickly and flexibly carry out their research. Parameters measurement system has been designed and methodology created. Analysis of the parameters measurement system and methodology is presented. Components and topologies have been selected based on parameters measurements for different solution variants. Preliminary ultrasound spectroscopy measurements have been carry out using the designed ultrasonic signaling system. |
