  1. Introduction to Fiber Optic Sensors The fiber optic sensor has an optical fiber connected to a light source to allow for detection in tight spaces or where a small profile is beneficial. The fiber-optic cable that is connected to the amplifier allows the sensor to reach areas inaccessible to standard photoelectric sensors. The sensor emits, receives, and converts the light energy into an electrical signal. … Light bounces off the fiber walls of fiber-optic cable.

  2. Principles of Fiber Optic Sensing 1 2 3 Light Modulation Signal Detection Data Interpretation The physical parameter alters the light traveling through the fiber. Changes in the light signal are detected and analyzed. The detected signal is converted into a meaningful measurement.

  3. Types of Fiber Optic Sensors Intrinsic Sensors Extrinsic Sensors Hybrid Sensors The optical fiber itself acts as the sensing element. A separate sensing element interacts with the optical fiber. Combine elements of intrinsic and extrinsic sensing techniques. • Fiber Bragg Grating Sensors • Intensity-Based Sensors • Fiber Optic Microphones • Interferometric Sensors • Polarimetric Sensors • Bio-sensing Applications
