Abstract
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.
