The optical fiber sensor is composed of a light source, an incident fiber, an exit fiber, an optical modulator, an optical detector, and a demodulator. The basic principle is that the light of…

According to the principle that light is modulated in optical fiber, optical fiber sensors can be divided into intensity modulation type, phase modulation type, polarization modulation type, frequency modulation type, and wavelength modulation…

Optical fiber connectors are divided into optical fiber fixed connectors, that is, fixed connections between the relay sections. The methods of fixing the joints include the fusion welding method, the V-groove method, the…
