The invention discloses a method for light splitting, imaging and synchronous phase shifting in optical interferometry: the polarized laser beam output by a laser light source is expanded to obtain a linearly polarized plane light source, and then enters a plane polarized light interference system to obtain a test wave surface An interference field that is co-beamed with the reference wave surface and whose polarization directions are perpendicular to each other. The interference field beam is divided into four beams with uniform spatial distribution and uniform intensity after passing through a quarter-wave plate and a combined prism beam splitting system. The four beams pass through the analyzer After that, it is projected onto the CCD target surface, so that four interference fringe patterns with a phase shift of 90 degrees can be obtained after one high-speed sampling. At the same time, a device for implementing the method is also disclosed. The method and device of the invention have clear principle, simple method and miniaturization of the device. The on-site dynamic measurement of high-precision optical interference is realized, and the measurement process is simpler and more convenient.
