Below, the Inline Closure manufacturer will introduce the types of fiber optic sensors?

1, fiber optic sensor
The basic principle of fiber optic sensors is that the change in transmitted light intensity in an optical fiber is caused by the physical quantity to be measured. The physical quantity is measured by detecting the light intensity. Traditional industrial engineering sensors include large voltage and current sensors for the power industry. The electro-optical and magneto-optical effects of the fiber are measured. The fiber bounce effect of FBG devices and the use of stress sensors have been widely used for stress monitoring.

2, optical pickup fiber sensor
The optical pickup fiber optic sensor uses an optical fiber as a probe to receive light that is radiated by or reflected and scattered by an object to be tested. Optical fiber sensors can be divided into optical focus fiber sensors, phase modulation fiber sensors, polarization modulation fiber sensors, and wavelength modulation fiber sensors, according to modulated light wave parameters.

3. Amplitude modulation sensing fiber optic sensor
It uses various factors caused by external factors to detect various parameters of the fiber, and there are many ways to change the intensity of the fiber. Changing the microbend state of the fiber is one of them. The fiber optic microbend sensor of the fiber optic sensor manufacturer uses the microbending loss in the fiber to detect changes in external physical quantities. It is the application of multimode fiber in microbend. Some core mode energy will be converted into the overmold energy principle, and the displacement or vibration can be measured by measuring the energy of the cladding mode or the energy of the core mode.
