Abstract
Spontaneous parameter down-conversion is exploited as a tool for absolute quantum efficiency calibration of photon detectors working in the photon-counting regime. This paper innovatively proposes a quantum efficiency correction model by analyzing the effects of after-pulse, double channel bandwidth matching and other factors on double channel coincidence counting. This experimental system shows the minimum deviation of quantum efficiency is 0.17% and detector quantum efficiency calibration accuracy better than 1.23%. The development of this new radiation calibration technology will play an important role in the future space radiation reference source and high-precision satellite radiation calibration, quantum communication and low-light level fields, environmental monitoring and climate research programs.
