识别一个快速运动的塑料纤维束中的一个粗厚点 应监测一个快速运动的塑料纤维束中的粗厚点。为此将一个透射光导体头置于纤维束正常走向的下方不远处,使得光束在纤维束的正常走向上不会衰减。而当出现粗厚点时,光束会被局部遮盖,这反过来又会导致接收器信号减弱。
Detection of a ravel in a fast moved plastic fiber bundle
A ravel in a fast moved plastic fiber bundle should be detected. At this, an optical fiber through beam head is placed in way, that the normal plastic fiber bundle stream does not cover the optical beam. However, if a ravel appears, the optical beam will be partly interrupted and this leads to a decrease of the receiver signal.
