Faserende+Faserverstärker

This is a metal hose protected fiber optic head, serving as the “front-end probe” of the fiber optic sensor, which works with a fiber amplifier to perform detection. The optical fiber built into the fiber head is connected to the fiber amplifier at one end and aimed at the detection area at the other. The light signal emitted by the amplifier is transmitted through the optical fiber to the probe end. After contacting the target object, the reflected/transmitted light travels back along the optical fiber to the amplifier, completing the detection process.
