Abstract

Low (up to 40 Hz) and high frequency (approximately 2.0 kHz) piezoelectric choppers of the IR radiation are considered. The methods and results of calculation of the amplitude- frequency characteristics, mechanical stress-strains state and temperature heating of PZ flextensional actuators are given. The obtained voltage and frequencies valuations realize the maximum of electromechanical coupling and minimum heating at resonant oscillations with equal amplitude of strains.
