Measurement System of Pyroelectric Coefficient for Pyroelectric Material Using Dynamic Current Method

Abstract:

A dynamic current method used to measure pyroelectric coefficient (p) for pyroelectric material is described in detail in this paper. The hardware part of the system includes pre-converting circuit, post amplifier circuit, wave-filter circuit, analog-to-digital conversion circuit, temperature test circuit and LCD display panel circuit. The maximum magnification time of amplifier circuit of system is 11300 and the band-stop frequency center for wave-filter circuit is 50 Hz and it's second harmonics 100 Hz. Finally, the measurement system is used to test p parameter of LiTaO₃ crystal slice. The lowest p parameter of LiTaO₃ crystal with a value of 6.08×10^-9 C/cm^{2 o}C is achieved at 32.5°C.
