摘要:

相关光子是由强激光泵浦非线性晶体的自发参量下转换效应产生的。从两方面阐述了对探测器量子效率的定标,包括对光子计数型探测器和模拟探测器。针对每一方面详细地介绍了目前主流的定标方案,并给出了其详细的理论表达式及实验方案。根据理论分析其优点及缺点,并与传统的定标方法进行比较。重点对模拟探测器量子效率的定标在不同方案下的应用范围及表达式进行总结,总结了对探测器定标的最新进展,分析了这些方法的基本思想。提出下一步研究方向及可实现的方法,展望该领域的发展前景。

Abstract:

Correlated photons are generated by the spontaneous parametric down-conversion (SPDC) effects of nonlinear crystal pumped by highly intense laser. Two different quantum efficiency calibration methods of analog detectors and photon-counting regime are presented, including the theoretical expression, experimental plan, the advantages and disadvantages when compared with traditional methods. The application range and expression of the quantum efficiency of analog detectors in different calibration methods, as well as the last advances in photoelectric detectors calibration field and fundamental ideas are summarized. The next direction of investigation and the method of realization are mentioned. The future of this field is also viewed.

Key words: correlated photons, analog detectors, photon-counting detectors, the quantum efficiency, the absolute calibration
