Transient Quantitative Identification Algorithm Based on Laser Impulse Response

In order to improve the measurement accuracy of transient heat flow based on laser pulse response technology, a dynamic calibration algorithm fiber semiconductor is proposed. The system uses high-power generate modulated excitation, and quantitatively detects energy in form pulsed radiation. light intensity source adjusted by homogenization spot, completed with Gardon meter. data acquisition card signal analysis circuit are used realize high-speed calculation signal. Using quantitative identification algorithm, test performance circular foil meter GD series tested calibrated. simulation system’s ability modulate verifies feasibility modulation. A lasers established experiment. curve noise after passing this smaller higher, which effectiveness algorithm. can be applied field rapid energy.
