摘要：

A high transmittance, flat energy spectrum response detector is designed. The relationship between the image and absolute intensity of the pulse radiation is established via a detector, which simplifies the calibration of the absolute measurement in the imaging system. And a new technical approach to the absolute imaging diagnosis for the pulsed radiation is developed. The experiments show that the uncertainty of the absolute intensity measured by this technology is 33%.
