Abstract
An optical sheet is moved by a conveyor belt, and at least one beam is configured above the conveyor belt. When the beam is intersected by the moving optical sheet, the optical sheet is determined to be curled. The present invention achieves automatic in-line measuring of optical sheet curls by precise optical measurement and thus enhances measuring accuracy and raises measuring speed.
