| 英文摘要 | PURPOSE:To obtain the light of the same intensity by providing two light emitting elements and one light accepting element in the same waveguide path to change for the preparatory light emitting element. CONSTITUTION:The light wave 4 is emitted from an end plane of the light waveguide path 3. A part of the light wave 4 goes to the light detecting element 2 thereby monitoring the intensity of the light. The intensity of the light emitted to the backward of the main light emitting element 1 is detected by the light detecting element 2. The driving power source E is connected to the main light emitting element 1 and the preparatory light emitting element 1' through the switches S1 and S2. The output of the light detecting element 2 can be seen by the meter M. The light wave is emitted forward and a part of the light wave is detected by the light detecting element 2. When the light which transmitted through the waveguide path ceases and the meter M indicates zero, the switch is changed over to flow the driving current to the preparatory light emitting element 1' provided auxiliary. The light emitted from the preparatory 1' is confirmed by the light detecting element 2. |
