OPTICAL SENSORS: OPERATING PRINCIPLE AND APPLICATIONS.
Keywords:
Optic sensor, passive optic, active (laser), fiber optic, spectroscopic, plasmonic.Abstract
This article analyzes optical sensors, their working principles, and applications in key fields such as medicine, industry, and environmental monitoring. Optical sensors operate by detecting changes in light intensity, wavelength, or phase. The study focuses on sensor classification, spectroscopy-based detection, and modern technological trends such as fiber Bragg grating sensors and plasmonic biosensors.References
