Image-free motion parameter acquisition has been continuously studied in recent years. This image-free method can effectively overcome the deficiencies of traditional imaging methods and improve the real-time and fast acquisition ability of motion parameters. However, existing methods only focus on the acquisition of motion position parameters. Herein, an image-free multi-motion parameter detection method is proposed for in-plane rotation of 2D object. A moment-modulated pattern was constructed to illuminate the moving object, and detected intensities were used to synchronously obtain the moving position and rotation angle. Numerical simulations and experiments verified the effectiveness of the proposed method, which provides a new idea for image-free multi-motion parameter acquisition.
