Principle of optical fiber MEMS sensing technology
Fiber optic MEMS sensing technology is a cutting edge technology based on 21st century micro/nano manufacturing technology. It combines MEMS micro/nano processing technology with fiber signal detection technology to miniaturize, multi-function and intelligentize fiber optic sensors. And the level of reliability has increased to new heights. It includes two components: MEMS photosensitive chip and fiber signal detection unit.
DTS temperature measurement principle
The basic principle of DTS fiber distributed temperature measurement technology is to use the Raman scattering and optical time domain reflectometry (OTDR) techniques to obtain spatial temperature distribution information when transmitting laser light in an optical fiber.
Fiber Bragg Grating Sensor Principle
Fiber Grating (FBG) is a laser irradiation method. In the sensitive area of a centimeter length length of a quartz single mode fiber, the grating period is changed when the temperature, stress, strain or other physical quantity of the fiber grating is changed. Or the refractive index of the core will change, so that the wavelength of the reflected light changes. By measuring the change of the wavelength of the reflected light before and after the change of the physical quantity, the change of the physical quantity to be measured can be obtained. The real-time vibration waveform is monitored while the engine is on.
