Abstract
A method for measuring deformation of a shaft by a device includes illuminating a pattern applied on the shaft before the deformation is applied; and detecting a first reference position by detecting the radiation reflected by the pattern, after the deformation is applied illuminating the pattern and detecting a second reference position by detecting the radiation reflected by the pattern. Based on the distance between the first and the second reference positions, the shaft circumferential deformation and/or torque is determined.
