Abstract

A one-shot method to describe the 3D shape of a rotating object is evaluated. A sinusoidal fringe pattern is illuminated on the rotating object. Fringes on the rotating object observed by the digital camera are blurred by the motion. The blurred fringes are analyzable to retrieve the profile of the rotating object.
