Abstract
A measuring apparatus includes a holding unit and a measuring unit. The measuring unit includes a first optical fiber for transmitting light emitted from a light source, a branching member for branching the light transmitted through the first optical fiber to at least two measuring optical fibers, a plurality of heads including respective beam condensers for converging the light branched by the branching member onto a measurand, a shutter device for shifting timings of application of the light applied from the heads to the measurand, a second optical fiber branched from the branching member and transmitting returning light reflected from the measurand, a spectroscopic unit having a light detector for detecting the returning light, and a controller for controlling the shutter device to control the timings of application of the light applied from the heads to the measurand and controlling the light detector to detect the returning light individually.
