Abstract

The invention relates to a phase measurement device of a beam splitter, which comprises a phase measurement device of an unpolarized beam splitter and a phase measurement device of a polarized beam splitter, wherein the phase measurement device of the unpolarized beam splitter comprises an unpolarized beam splitter to be measured, two polarized beam-splitting prisms, four photoelectric detectors and an oscilloscope; and the phase measurement device of the polarized beam splitter comprises a polarized beam splitter to be measured, two one-half wave plates, two polarized beam-splitting prisms, four photoelectric detectors and an oscilloscope. The phase measurement device can measure the phase relationship of two orthogonal components containing a vertical component (s component) and a parallel component (p component) of transmission light and reflected light of light waves after passing through the beam splitter. The invention is simple in measurement and easy to operate.

Description

technical field [0001] The invention relates to the phase measurement of light waves, specifically measuring the phase relationship between two orthogonal components of the transmitted light and reflected light after the light wave passes through a beam splitting device, including a vertical component (s component) and a parallel component (p component). Background technique [0002] In many optical systems, it is often necessary to use a beam splitter to split a beam of light into two beams of light. The commonly used beam splitters include beam splitters, beam splitters, and beam splitter prisms, which are widely used optical components. For this kind of beam splitting device, almost all devices only measure the splitting ratio, that is, the light intensity energy ratio of the two split beams, and do not measure the phase change relationship of the beam after passing through the splitting device, but in some applications , such as spatial coherent detection, laser radar, e...
