Abstract In this study, a sampling moire method in which parallel laser lines
were generated in a camera using a diffraction grating was proposed. A green
laser of line projection function, a diffraction grating and an industrial camera
were used as an experimental device. Object images with laser line projection
before and after displacement were taken by the camera. Displacements that
calculated by a sampling moire method and a method of averaging center-ofgravity were be compared. Results show that the proposed method is more
precision than method of averaging center-of-gravity. More >
