Popis:	The paper deals with the design and principles of the hybrid Brillouin-Rayleigh sensing system. The system is capable of separating strain and temperature values in single SM fiber and offers spatial resolution as high as 2 cm. Furthermore, the paper introduces a method to determine required separation coefficients for optical fiber cables. Finally, it presents several validation examples and results of industrial applications.
