Photonic sensors are devices that use light to measure physical quantities such as temperature, pressure, strain, and chemical composition. They are widely used in various industries due to their high sensitivity, fast response, and immunity to electromagnetic interference. Proper calibration of these sensors ensures accurate and reliable measurements in real-world applications.
Industrial Temperature Monitoring
Photonic temperature sensors, such as fiber Bragg gratings (FBGs), are used in industries like power generation and manufacturing. They provide precise temperature readings in harsh environments where traditional sensors may fail. Calibration involves comparing sensor output with standard temperature references to maintain accuracy over time.
Structural Health Monitoring
In civil engineering, photonic sensors monitor strain and stress in bridges, buildings, and aircraft. These sensors detect minute changes in deformation. Calibration ensures that measurements reflect true structural conditions, often involving baseline measurements and periodic recalibration.
Chemical and Biological Sensing
Photonic sensors detect chemical and biological agents in industries like healthcare and environmental monitoring. They measure changes in light properties caused by interactions with target molecules. Calibration involves using known concentrations of substances to establish accurate measurement scales.
