Laser Impulse Detection System Based on Piezoelectric Film Sensor

Abstract:

In order to use relatively simple approach to detect the laser impulse chose the polymer organic thin-film piezoelectric sensor with high sensitivity, wide dynamic range, good frequency band response and other good characteristics, designed the subsequent amplifying and detecting circuit. The sensor converted non-electricity quantity of laser impact to measurable electricity quantity via piezoelectric effect and the amplifier circuit. After the detection system processing, the final output signal was displayed by the oscilloscope and made simple analysis of the results.
