Abstract
A method of sensing the pitch or relative location of a lenticular lens on a sheet of transparent lenticular material of the type having a repeating pattern of cylindrical lenses on one side and a flat opposite side, comprising the steps of: forming a beam of light; focusing the beam of light into a spot smaller than the pitch of the cylindrical lenses onto the lenticular material; moving the lenticular material relative to the beam in a direction perpendicular to the axes of the cylindrical lenses to modulate the angle of reflection or refraction of the beam of light; and sensing the position of the modulated beam of light to determine the pitch or relative location of lenticular material to the focused spot.
