Fiber optic signal transmission to sensor
Fiber-optic sensors use the physical properties of light when transmitting it via fiber-optic cable with glass or plastic fibers to detect objects. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of time. In 2023, researchers turned submarine cables into earthquake warning systems and gave electric vehicles "optical nerves" to prevent battery failures. Fiber-optic sensors detect objects and conditions by directing light to a test object and evaluating the intensity change of the returning light.
