内容記述 |
In the optical system utilized in nuclear fusion reactors, it is possible that the reflectance of the mirrors positioned within the vacuum vessel may undergo alteration as a consequence of the deposition of impurities or corrosion. To address this issue, a methodology was proposed whereby light is introduced from outside the vessel, and the transmittance of the optical system is determined by measuring the light reflected by a retro-reflector that is temporarily placed at the tip of the optical system. However, as the reflectance of the retro-reflector itself is not always constant, a reliable method for absolute sensitivity calibration has yet to be established. In this study, we developed a method for measuring the reflectance of the cat’s-eye retro-reflector and, consequently, the transmittance of the optical system. This entailed an analysis of the differences in reflection positions and times within the cat’s-eye retro-reflector. |
