给出了表示线性无损无源分束器作用的酉算符。这一推导是基于一种基本的群论方法，它允许我们通过入射光束的斯托克斯算符来理解这种作用。用这个算符举例说明了分束器中噪声的耦合。
The unitary operator representing the action of a linear lossless passive beam splitter is presented. The derivation is based on an elementary group-theoretical approach that allows us to understand this action in terms of the Stokes operators for the incident beam. This operator is used to illustrate with some examples the coupling of noise in the beam splitter.
