The voltage response of pyroelectric detectors to pulse radiation was analyzed, Using lock-in amplifier based on correlation detection principle, response voltage was detected. A dynamic response measuring system of pyroelectric detector parameters was set up. Software was programmed based on LabVIEW. The proposed measuring system is used to measure the voltage responsibility and normal detect ratio of pyroelectric detector to pulse radiation. The result shows that it is a practical automatic system for measuring pyroelectric detector parameters.
