| 摘要 |
The present invention relates to a structure in which a sensor includes a first area and a second area upon which dispersed first and second lights are focused. The first and second areas are disposed in a dispersion direction or a direction perpendicular to the dispersion direction. A distance between the first and second areas is adjusted by using a distance between a plurality of fiber ends from which a plurality of combined lights exit and an optical magnification at a detecting section. |
