Photonics sensors are spurring the development of new, powerful sensing instruments for a wide range of applications.
Main sensor types are:
- Proximity laser and IR sensors for detecting the presence of nearby objects used, e.g., in smartphones, manufacturing and LiDAR systems for autonomous driving
- Pyrometers use the colour spectrum of the visible light to determine high temperature measurements at a distance mainly for oil and gas and heavy industry.
- Photodetectors transform light into electrical signals for use, e.g., in video imaging, optical communications, night-vision and gas sensing.
- Infrared sensors use unique adsorption spectrums for real-time detection of, e.g., diseases and the emission of toxic gases.
- Fibre optic sensors reflect particular wavelengths of light for highly sensitive monitoring of extremes of pressure and temperature for heavy industry, and vibrations for structural health monitoring.
