作为二元判定问题的干涉测量

Interferometry as a binary decision problem

Matteo G. A. Paris

摘要:

二元决策理论已被应用于一般的干涉问题。根据内曼-皮尔逊准则,针对辐射场的不同相位增强状态考虑了最佳检测方案,并评估了相应的最小可检测相移界限。在携带相位信息的信号模式的光子数波动方面,也得到了干涉精度的一般界限。

英文摘要:

Binary decision theory has been applied to the general interferometric problem. Optimal detection scheme-according to the Neyman-Pearson criterion-has been considered for different phase-enhanced states of radiation field, and the corresponding bounds on minimum detectable phase shift has been evaluated. A general bound on interferometric precision has been also obtained in terms of photon number fluctuations of the signal mode carrying the phase information.
