Abstract
PURPOSE: To measure the quantity of movement in the width direction of a metallic beltlike body accurately by a method wherein a rotatory polyhedral mirror is mounted at the location of the focus of a parabolic mirror, the luminous energy of the metallic beltlike body is scanned, and converted into electric signals by means of an infrared sensor and a location of an edge is detected.
CONSTITUTION: A parabolic mirror 2 is installed to the upper or lower section of a metallic beltlike body 1 while a rotatory polyhedral mirror 3 is set up at a location of the focus thereof. The luminous energy of the metallic beltlike body 1 is inputted to an infrared sensor 4 through the parabolic mirror 2 and the rotatory polyhedral mirror 3, the value is converted into electric signals and the location of an edge is measured continuously by means of a signal processor 6 during the movement of the beltlike body 1 by the reference signals of a reference location detector 5 separately mounted. Thus, the quantity of the movement of the metallic beltlike body 1 can be measured in high accuracy because light energy signals which the rotatory polyhedral mirror 3 scans do not change.
