    • Sensitivity kernels for transmission fibre optics 

      Fichtner A., Bogris A., Bowden D., Lentas K., Melis N.S., Nikas T., Simos C., Simos I., Smolinski K. (2022)
      Fibre-optic sensing based on transmission offer an alternative to scattering-based distributed acoustic sensing (DAS). The ability to interrogate fibres that are thousands of kilometres long opens opportunities for studies ...

    • Theory of phase transmission fibre-optic deformation sensing 

      Fichtner A., Bogris A., Nikas T., Bowden D., Lentas K., Melis N.S., Simos C., Simos I., Smolinski K. (2022)
      We present a theory and conceptual examples for fibre-optic deformation sensing based on phase changes of transmitted light. As a first result, we establish an exact relation between observable phase changes and the ...
