与电磁场单模相关联的相位与光子数互补。这个简单的想法引导我们构造相的概率密度。相位算符不能在通常无限的希尔伯特空间中精确地表示，但可以在它的子空间中构造，并且如果与适当的极限过程一起使用，则可以提供一个有效的相位表示。我们引入了厄米光学相位算符，并描述了它的一些最重要的性质。我们还简要讨论了相位问题和相位测量问题的一些替代方法。这篇论文以一份详尽的参考书目结束。
Abstract The phase associated with a single mode of the electromagnetic field is complementary to the photon number. This simple idea leads us to construct a probability density for the phase. The phase operator cannot be represented exactly in the usual-infinite Hilbert space but can be constructed in a subspace of it and provides a valid representation of phase if used together with a suitable limiting procedure. We introduce the Hermitian optical phase operator and describe some of its most important properties. We also provide brief discussions of some alternative approaches to the phase problem and to the question of phase measurements. The paper concludes with an extensive bibliography.
