The Working Principle and Basic Structure of Fiber Optic Sensor

Working Principle

Fiber optic sensors guide light through optical fibers, using the propagation characteristics of light (such as reflection, refraction, interference, polarization, etc.) to achieve signal transmission and measurement. When the state of the object is measured or the environment changes, the characteristics of the light change, and the sensor detects these changes in light to sense the external physical quantity.

Basic Structure

• Optical Fiber: The medium used to transmit light signals, is the core component of the sensor. Fiber optics are generally made of glass or plastic, with high transparency and anti-interference ability.
• Light source: Usually an LED or laser, used to provide an incident beam of light.
• Detector: Used to receive and analyze the changing light signals and convert them into electrical signals.
• Signal Processor: Amplifies, filters, and digitizes the electrical signals to finally output usable data.

Classification of Fiber Optic Sensors

Fiber optic sensors can be classified into various types according to their function and structure:

1. Through Beam Fiber Optic Sensors: Light travels in a straight line between the transmitter and receiver, suitable for long-distance measurements.
2. Diffuse Reflective Fiber Optical Sensors: Working with light reflected from an object, suitable for detecting the presence or absence of an object.
3. Coaxial Fiber Optic Sensors: Transmit and receive on the same fiber, suitable for detection in a narrow space.

Features and Advantages of Fiber Optic Sensors

• Non-contact Measurement: Fiber optic sensors do not need to be in direct contact with the object to be measured, avoiding the interference and wear and tear problems caused by contact.
• Strong Resistance to Electromagnetic Interference: Fiber optics use light as a medium to transmit signals and are not subject to interference from electromagnetic fields, which makes them excellent in high electromagnetic environments.
• High Sensitivity and Accuracy: Thanks to the physical properties of light, fiber optic sensors can capture extremely subtle changes, and the measurement accuracy is much higher than that of traditional sensors.
• Wide Applicability: Fiber optic sensors can be used in extreme environments such as high temperature, high pressure, corrosive environments, and nuclear radiation scenarios.
• Flexible Installation: The fiber optic itself is small and flexible, suitable for installation in narrow or complex equipment.
• Long Lifetime: No mechanical wear parts, fiber optic sensors have stable performance and high reliability after many times of use.

The Importance of Fiber Optic Sensors

Fiber optic sensors play an important role in modern industrial production, which promotes the efficiency of automated production lines and precision breakthroughs. For example, in the manufacturing industry, fiber optic sensors are used to monitor the displacement, speed, and other key parameters in the production process in real-time to improve the product qualification rate. In the energy industry, fiber optic sensors are used to monitor the pressure and temperature of pipelines to effectively prevent accidents.

In the medical field, its sensitivity and miniaturization characteristics help high-precision surgery and equipment performance monitoring. In transportation, fiber optic sensors monitor stress changes in bridges, tunnels, and other infrastructure to ensure public safety. Fiber optic sensors are not only an important part of Industry 4.0 but also one of the cornerstones of future smart manufacturing and smart city construction.

Fiber optic sensors have become one of the core technologies for the development of intelligence because of their excellent performance and wide range of application scenarios.
