摘要:A wavelength variable light source emits a light whose wavelengthscontinuously change from a preset start wavelength up to a stop wavelength to a
measuring object. A timing information output section generates timing informationshowing emission timings of lights emitted from the wavelength variable light source andhaving start and stop wavelengths and a plurality of wavelengths obtained by delimitingthe wavelengths between the start and stop wavelengths in predetermined steps. A lightreceiving section receives the light output from the measuring object and outputs asignal showing a measured value of a received light. A plurality of amplifiers receive thesignal output from the light receiving section and amplify the signal at each
predetermined amplification factor. A signal selecting section selects one signal kept in apredetermined measuring range of signals amplified by the plurality of amplifiers at theeach predetermined amplification factor and outputs the one signal as a measured valueof a light of a wavelength decided in accordance with corresponding timing information inthe information output from the timing information output section.
