Requirements of the light source optical fiber sensor

Fiber optic sensors, fiber-optic thin and long , when the light in which the normal transmission , and meet the measurement requirements, and ultimately, the light source has been requested , and the structure and properties of the light source also proposed certain requirements . Well, now give you some fiber sensors What are the requirements for light bars . The first is due to limited fiber optic sensor structure , requiring light small, easy and fiber-coupled light source have enough brightness to increase Motor Sensors output optical power. Wavelength of the light emitted by the light source should be suitable to reduce the light transmission in the fiber of the energy loss. Second light work requires good stability, low noise, can be long-term work continued at room temperature , the light source to be easy to maintain , easy to use .
