Abstract

PURPOSE: To accurately obtain the profile of the surface being measured in a short time by scanning the surface being measured with a laser beam and condensing the scattered light from the surface being measured with a photo detecting optical system having a specified aperture diameter.
CONSTITUTION: In the case of measuring the top profile of a blast furnace, a light transmission window 3 and a photo detecting optical system 4 are provided in a pair at the portion of the shoulder of a blast furnace 1. The pulse laser beam 6 of a YAG laser 5 as a light source is reflected with a scanning mirror 7 and is entered into the furance through the light transmission window 3. The scattered light from the furnace top surface 2 is condensed and the loci of the images obtained by the diode array 8 disposed on the focal plane thereof are examined, whereby the profile of the furnace top surface 2 may be measured. In this case, if a similar measurement system is so provided concerning with other sections as well as to obtain the sectional profiles in orthogonal two directions, the profile may be obtained more accurately.
