| Zusammenfassung: | One or more optical fibers are provided with different numerical apertures for differently transmitting light from an object. Light is thus transmitted for a given range at a predetermined ratio corresponding to a difference between the different numerical apertures. That ratio is varied by variations in the range. The varying ratio is detected and a range finder operation is performed in response to that detected varying ratio. |
