Abstract
From a single material of unpolarized piezoelectric transducer, cut away are a piezoelectric transducer for fabrication of a probe and a piezoelectric transducer for observation of polarization states. Both the piezoelectric transducer for fabrication of a probe and the piezoelectric transducer for observation of polarization states are simultaneously subjected to the polarization processing (or depolarization processing) while observing polarization states of the piezoelectric transducer for observation of polarization states.
