Abstract: When a beam falls on a plane parallel glass plate, the beam undergoes multiple reflections at the two surfaces. Thus if we use the plane parallel glass plate without an antireflection coating as a beam spUtter, we must eliminate stray light caused by multiple reflections; otherwise it interferes a major reflection ray and hence gives rise to noise. When the thickness of the beam splitter is thin, it is difficult to remove the stray light. In this paper, we investigate the effects of the thickness of the beam splitter on the SNR in heterodyne detection, taking into account the stray light of a local oscillator beam.
