Study on 3D shape and deformation measurement of a radiator fan based on high-speed binary defocused fringe projection

The binary defocused fringe can overcome the nonlinear effect of an ordinary commercial digital projector and generate a good sinusoidal light field. In this paper, the binary fringe encoding method was chosen to complete the high-speed fringe projection using a DLP Lightcrafter 4500 model in dynami...

Further deformation analysis of the measured radiator fan blade and rotating shaft is helpful to improve the performance of the radiator. The experimental results on a tested radiator fan with the rotation speed of 4800rpm identified the validity of the presented setup, and this method can effectively expand the application of dynamic 3D shape measurement.
