Mechanism of action
- Measurement techniques in photonic systems are based on the interaction of light with measured objects. Depending on the application, they can use phenomena such as reflection, refraction, interference, diffraction, or absorption of light. For example, spectrometers analyse the spectral composition of light passing through a sample to determine its chemical or physical properties. Interferometers measure changes in distance by comparing the phases of two light beams. Beam analysers and profilometers study the properties of a beam or surface based on precise measurements of intensity distribution and optical structure. In each case, the measurement results are processed by electronic circuits for further analysis and visualisation.
