<p><P>PROBLEM TO BE SOLVED: To provide a multipoint measuring apparatus by which a plurality of points are simultaneously measured by selecting and changing over an optical path even when only a single measuring channel of an optical measuring device exists. <P>SOLUTION: The multipoint measuring apparatus is provided with a light source 1 and a light source 2; a plurality of projection fibers 5, 6 used to irradiate beams of light from the light sources at the plurality of points; a plurality of light receiving fibers 8, 9 used to collect beams of transmitted light, reflected light, scattered light and the like from the plurality of points; a beam selector 10 composed of a rotating disk 12 having one transmission hole used to pass the beams of light collected by the plurality of fibers 8, 9 to any one light receiving fiber; and an MCPD 4. Consequently, when the rotating disk 12 is turned and when the transmission hole is brought to, and made at a standstill in, a position passing the beams of light in a channel to be measured, the beams of light in the light receiving fiber are transmitted and measured. When the beams of light in other channels are measured, the rotating disk is turned by a prescribed angle. <P>COPYRIGHT: (C)2004,JPO</p> |
