Mechanism of action
- Fibre optic technologies use the phenomenon of total internal reflection, which enables light to propagate inside the optical fibre with minimal losses. Transmitting modules convert electrical signals into light pulses, which are transmitted through optical fibres and received at the end by optical detectors. In the case of laser technology, a coherent beam of light is produced by excitation of the active medium, which leads to the emission of radiation with high energy density. With the ability to control beam parameters, the lasers can be used for precision industrial processes and metrology measurements. Depending on the application, these technologies can be used as data transmission systems, diagnostic tools, or material processing equipment.
