利用费曼路径积分理论研究了两个不同光谱的独立光子在Shih-Alley/Hong-Ou-Mandel干涉仪中的二阶干涉。如果光子对于所采用的探测系统是不可区分的，则对于具有不同光谱的光子存在二阶干涉图案。分析了不同光谱光子产生二阶时间拍频的条件。文中还讨论了探测系统的响应时间对观测到的二阶干涉图样的影响。这是量子力学中的测量依赖于所采用的测量仪器的直接结果。所得结果有助于理解不同方案下的双光子干涉物理。（文件）
The second-order interference of two independent photons with different spectra in a Shih–Alley/Hong–Ou–Mandel interferometer is studied in Feynman's path integral theory. There is a second-order interference pattern for photons with different spectra if the photons are indistinguishable for the employed detection system. The conditions to observe the second-order temporal beating with photons of different spectra are analyzed. The influence of the response time of the detection system on the observed second-order interference pattern is also discussed. It is a direct result of that measurement in quantum mechanics is dependent on the employed measuring apparatus. The results are helpful to understand the physics of two-photon interference in different schemes.(paper)
