- ItemStudium piezoelektrických kruhových bimorfů pomocí interferometru(Technická Univerzita v Liberci, 2006) Franc, LukášThe aim of this bachelor thesis is study of piezoelectric circular bimorphs. The measured samples are made of soft piezoelectric PZT ceramics APC850. Discs are consisted of two circular plates with different thickness. There are information about piezoelectric effect and materials for these applications in the first part of thesis. The special chapter is engaged in polycrystalic PZT ceramics. There are used Michelson and Mach-Zehnder interferometers for measurement of very small displacements by surface scanning. The measurement by Twyman-Green interferometer is only informative. There are compared measured values and calculated ones at the end.
