This invention discloses a system and method for measuring the combined Doppler frequency shift of a vortex beam. The system includes, in sequence, a frequency-modulated light source module, a superimposed vortex beam generation module, a mode selection and purification module, a moving target module, and a signal receiving and processing module. This invention, by constructing a suitable vortex beam measurement system, measures the combined Doppler frequency shift of a complex moving object with linear and rotational velocities by changing the topological charge and light frequency, based on the Doppler frequency shift formula, thereby obtaining the linear and angular velocities of the target object. Based on the combined Doppler effect of vortex beams, the measurement light consists of superimposed vortex beams with opposite topological charges. By fully extracting motion information from the structured light interference field, the multidimensional motion information of a class of objects undergoing complex motion is determined. The extraction method is simple, direct, and highly operable. The optical path design of this invention is simple, using fewer complex optical components and equipment, making it easy to operate and highly integrateable.
