Optical sensors are devices that convert light into electrical signals, enabling various detection and measurement applications across industries. From smartphones to industrial automation, these sensors play a crucial role in modern technology.
Optical sensors detect light, infrared, or ultraviolet signals using photodiodes or phototransistors. They measure intensity, wavelength, or polarization changes, providing data for systems like touchscreens or environmental monitors.
Common types include proximity sensors, ambient light sensors, and fiber-optic sensors. Each serves unique purposes, such as adjusting screen brightness or ensuring machinery safety.
Used in automotive, healthcare, and consumer electronics, optical sensors offer high accuracy, non-contact operation, and reliability. They enhance user experiences and improve operational efficiency.
