@@@@A spectral response system for infrared detector is designed. The principle of the system is also analyzed. The spectral response experiment of the pyroelectricity detector is performed with different temperature and frequency. The experiment result shows that the response of the pyroelectricity detector to infrared radiation is different,but the change trend curve of the voltage is similar. The theory of the infrared detector is thereby verified. The system has high measurement accuracy and stability,which can suppress the disturbance signal effectively and improve the signal-to-noise ratio of the system.
