Measurement of ultrasonic beam parameters
 Hlavatý, Radek ; Fialka, Jiří (referee) ; Beneš, Petr (advisor)
The work deals with methods of measuring the parameters of the ultrasonic beam generated by piezoelectric sensors. The theoretical part contains a literature search of methods for the analysis of the ultrasonic beam generated by piezoelectric transducers with dimensions of units of millimeters. The problematics of measurement using piezoelectric or optical fiber hydrophones is investigated in more detail. The scope of the practical part of the work is the design and implementation of measuring equipment that allows spatial analysis of the beam during propagation by a complicated signal path, for automotive level and concentration sensors of the company Vitesco Technologies s.r.o. The system uses a hydrophone method to measure the ultrasonic beam. Due to test measurements, the repeatability of the measured results is confirmed, the results are discussed in the end.
