Abstract
A way to achieve pyroelectric detector fast response compensation circuit based on the measurement of energy for high-repetition-rate pulse laser is proposed in this paper. The transfer function of the pyroelectric detector circuit system is derived adopting the linear model of the operational amplifier and the effect of input voltage and noise are ignored. Further, the noise characteristics and related factors are analyzed and their effects on the response speed, performance stability, signal gain and signal to noise ratio are discussed. Series of experiments were carried out to verify the reliability of the compensation circuit. This circuit has been applied in the pyroelectric detector system for measuring the energy and the power of high-repetition-rate pulse lasers. OCIS codes: 140.3538 040.1880
