Abstract
A system to detect the angle of pile lay of the fibers on the face side of a pile fabric by scanning the fibers with an infra red light source and measuring the intensity of the reflected infra red light beam. This is accomplished by using a rotating mirror system to deflect the infra red light beam onto the fabric and direct the infra red light beam reflected from the pile fibers on the fabric to a detector.
