A team of scientists from the Gdańsk University of Technology has constructed a fiber optic sensor using thin diamond layers. The device allows measurements in less accessible places and in difficult working conditions, in particular in the presence of strong electromagnetic fields.

The sensor was developed at the Faculty of Electronics, Telecommunications and Informatics. The device, due to the innovative covering the part of the mirror with a diamond layer becomes competitive in comparison to similar sensors available on the market. The invention also has other advantages: high sensitivity of measurements, wide range and good resolution.

Mirrors in traditional sensors are made of silver and are susceptible to scratches. The use of diamond coating gives the device resistance not only to mechanical damage, but also electromagnetic interference and aggressive chemical environments. The solution has been submitted for legal protection in the Patent Office.
