Doppler elfeet is an important knowledge point in the theoretical course of optoelectronic informationscience and engineering, and guiding students to combine theory and experiment through university physicsexperiments helps to help students understand the knowledge point, and also helps to cultivate studentsreseareh interest in physies and seientilie thinking through experiments, The solid velocity measuremen!experiment based on the laser Doppler ellect is introduced into the university physics experiment teaching,andthe experimental system is constructed , data processing and error analysis are carried out and the experiment isverified,Through the complete experimental process , students can exercise their hands-on ability and practicaproblem-solving ability ,and cultivate their seientifie research logical thinking and innovation ability.
