What types of fiber optic sensors are there? In fact, they can be classified according to their measurement objects, optical wave modulation methods, and sensing principles!

1. By Measurement Object: Divided into various types of fiber optic sensors such as stress, vibration, curvature, displacement, refractive index, temperature, liquid level, etc.

2. By Optical Wave Modulation Method: Divided into intensity modulation type, phase modulation type, wavelength modulation type, etc. Among them, intensity and wavelength modulation are the most common. Wavelength modulation fiber optic sensors have high measurement accuracy and strong stability, but they often require expensive demodulation systems, making them unsuitable for fields with high demand. Intensity modulation fiber optic sensors, although not as accurate as wavelength modulation, have low cost and simple operation, allowing this type of fiber optic sensor to occupy a place in the market.

3. By Sensing Principle: Divided into functional and non-functional fiber optic sensors. Sensors whose signal transmission systems and sensing devices are both composed of optical fibers are called functional (intrinsic) fiber optic sensors, also known as all-fiber sensors. At this time, the optical fiber is responsible for both signal transmission and sensing functions.
