Abstract

PURPOSE: To constitute an irradiation means compactly and to increase the width of a measurement range without increasing the diameter nor focal length of a convex lens by cutting off elliptic light only in the minor-axis direction by a slit formation member without cutting off the light in the major-axis direction.
CONSTITUTION: An irradiation means 3 shape the light from a light source into slit light L3, which is projected on the measured surface of an object 1 to be measured. An image pickup means 4 picks up the projection image drawn on the measured surface of the object 1 with the slit light L3, converts the image into the quantity of electricity, and outputs it. Further, a measurement unit 2 moves at right angles to the lengthwise direction of the slit light L3 while holding the constant distance to the object 1 by driving the arm 5 of an industrial robot to measure the whole shape of the object 1. Thus, the elliptic light emitted by a laser light source 10 is cut off by the slit formation member 30 only in the minor-axis direction without being cut off in the major-axis direction, so that the slit light is formed.
