Filed: 1985-06-14
Abstract: PURPOSE:To detect accurately whether water immersion occurs or not by providing a white light source at one end of an optical fiber and a optical demultiplexer at the other end and demultiplexing light into light of wavelength longer than specific wavelength and light of sensor wavelength, and controlling the white light so that the output of a photodetector for the light of shorter wavelength is constant. CONSTITUTION:The white light source 6 is provided at one end of the optical fiber 7 doped with P2O5 and the optical demultiplexer 8 is provided at the other terminal. The demultiplexer 8 demultiplexes light into light of <=1.0mum in wavelength and light of <1.0mum, and the output signal of the former light is made incident on the photodetector 9 and converted into an electric signal. The output signal of the latter light of <1.0mum, on the other hand, is inputted to a control system 12, which compares the shorter-wavelength light with a set value S and controls the output of the white light source 6 so that the light of shorter wavelength is constant. When water is present on the optical fiber 7, the output of the longer-wavelength light increases. For the purpose, the output of the shorter-wavelength light is made constant and the output of the longer-wavelength light is detected, so even if the optical fiber is curved, the presence or absence of water immersion is detected accurately by controlling the output of the white light.
