  • Fiber Optic Sensor Detection Through Glass

    Fiber Optic Sensor Detection Through Glass

    Fiber-optic pressure sensors small enough to fit inside a catheter can monitor intracranial pressure or blood pressure in real time. Glass-tipped fibers coated with chemically sensitive films serve as biosensors for detecting glucose, pH levels, or specific proteins. The sensor contains a light source (transmitter), typically an LED, and a photodiode (receiver). In civil engineering, FBG sensors are embedded directly into concrete during construction or bonded to steel reinforcement bars, providing continuous strain and temperature data throughout. Fiber optics with Built-In Indicators now allow for a quick status or alignment check by simply looking at the fiber head. Fibers are also used in confined areas since many models can be bent to fit precisely where needed.
