Three-Dimensional Shape Measurement for Rotating Blade Using Stroboscopic Structured Illumination
Three-dimensional digitized description of high-speed motion objects is very useful in study its motion and deformation. An optical method of rotating fan blade shape and deformation measurement is proposed, which was based on Fourier transform profilometry (FTP) and stroboscopic effect, and than is verified by experiment on a domestic electric fan. The results of authors' experiment proposed show that FTP can reconstruct the rotating fan blade shape efficiently and reveal the deformation clearly at different times by using stroboscopic light structured illumination. This method is suitable for wide use in studying rapid periodic motion.
