Claims

[Claims for Utility Model Registration] 1. A light source device that emits light with a plurality of emission wavelengths, a collimating optical system that converts the emitted light of each of the emission wavelengths from the light source device into parallel light beams, and this collimating optical system. an optical code plate that transmits or blocks each parallel light beam from the optical code plate by mechanical displacement, a focusing optical system that focuses each of the parallel light beams that have passed through the optical code plate, and synthesizes the light focused by this focusing optical system. an optical fiber that transmits the light combined by the multiplexer, and a photodetector that detects the amount of light transmitted by the optical fiber for each of the emission wavelengths. . An optical measurement system using an optical code plate, characterized in that mechanical displacement of the optical code plate can be detected as a binary signal. 2. An optical measurement system using an optical code plate according to claim 1, wherein a time-series output is obtained from the photodetector by temporally switching the light of the emission wavelength.
