Optical Transducers

Optical transducers are devices that convert physical quantities, such as pressure, temperature, or strain, into optical signals like changes in light intensity, phase, or wavelength. They enable precise and contactless measurement by translating variations in the environment into detectable optical responses. For example, fiber optic sensors use light traveling through a fiber to monitor structural health or environmental conditions, offering advantages like immunity to electromagnetic interference, high sensitivity, and remote sensing capabilities. In essence, optical transducers serve as the bridge between physical phenomena and optical systems, facilitating accurate and reliable data collection across various scientific and industrial applications.
