<P>PROBLEM TO BE SOLVED: To eliminate an influence of noise from the outside, and normally detect a component to be measured and measure the concentration of the component. <P>SOLUTION: In the optical measurement apparatus, a sensor section 3 and a converter (instrument body) 4 are connected to each other with optical fibers 2a to 2d, the sensor section 3 comprises: an optical system 31 for irradiating a sample with first light, receiving the reflected light, the transmitted light, the scattered light or the fluorescent light of the first light and converting the light to an electric signal; a light power conversion section 32 for converting second light to an electric power; an A/D converter 34 for converting the electric signal to a digital signal; and a modulator 36 for modulating third light on the basis of the digital signal. The converter (instrument body) 4 comprises: a power source section 41 for supplying an electric power; light-emitting sections 42a to 42c for emitting light by receiving the supply of the electric power and outputting the emitted light to the optical fibers 2a to 2d; a light-receiving section 43 for receiving the modulated light and converting the received light to an electric signal; and an output section 44 for outputting a measurement result on the basis of the electric signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
