Tips: How do diffuse reflective fiber optic sensors work?

A diffuse reflective fiber optic sensor is a sensor that transmits light signals through an optical fiber for non-contact detection. It uses the diffuse reflection of light with the surface of the target object to measure the position, presence or absence, or color characteristics of the object. When light is emitted from the fiber optic transducer's transmitter and hits the surface of the target object, part of the light is diffusely reflected back to the sensor's receiver. The sensor analyzes the state of the object's surface by detecting changes in the intensity of the returning light. These sensors are commonly used in industrial environments where precise inspection is required or where direct access is difficult, such as automated assembly lines, package inspection and quality control.
