<p><P>PROBLEM TO BE SOLVED: To provide an optical measuring device that has a simple constitution, allows accurate measurement in response to various measured objects, and reduces the man-days as well as time loss. <P>SOLUTION: The optical measuring device projects light of a light source to a measured object and measures properties, such as material, thickness, components, and moisture of a measured object. A light projection spot control means, having a plurality of slits with opening shapes corresponding to the shape of the measured object, is arranged in an image-forming position of the light from the light source. The spots are made to correspond to the shape of the measured object, thereby providing a large measuring light amount, having no waste from a required section of the measured object, and improving the measurement accuracy. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
