Abstract
PURPOSE: To accurately measure the thickness by a method wherein the laser focusing beam is irradiated obliquely on the glass band surface in the float molding room and the number of the interference fringe of the reflected beam is counted.
CONSTITUTION: Melted glass is supplied on bath 2 of fused metal in float molding room 1 and it is cooled to become glass band 4 of the specified thickness. Laser beam 12 of laser source 11 is irradiated obliquely upon the surface of glass band 4 through mirror M1, optical system 13 and light transmission window 16 of molding room 1. Reflected beam 17 containing that interference fringe is transmitted to the outside of molding room 1 through light transmission window 16. This reflected beam 17 passes through half mirror M2, is reflected at rotary mirror 18 and received in light receiver 20 via slit 19. The output of light receiver 20 becomes the pulse output of the number of fringes and it is counted by means of a counter, thus, the thickness is measured.
