Research area and interests

FSO signal propagation in the atmosphere

· Propagation modelling of optical waves

· Complete research of atmospheric impact on FSO link attenuation (particularly fog, rain, atmospheric gasses, refractivity index, structure index, wind turbulences etc.)

· FSO attenuation prediction

· Simultaneous measurement of FSO link attenuation on 830 nm and 1550 nm wavelengths on 60m path on a mountain observatory followed by data analysis and event analysis

· Measurement of relevant meteorological parameters (visibility, rain rate

refractivity index, 3 components of wind speed, cloud height etc.).

Other research activities

· radar meteorology (now finishing a 35 GHz FMCW cloud radar)

· radio wave propagation research

· meteorological parameter processing for radio wave propagation research

Research Facilities


· FSO experimental link operating on 830 and 1550 nm (second link will be installed soon)

· 2D videodistrometer (made in Joaneum research)

· 2 pieces of visibility and weather sensors (Vaisala) PWD11 and PWD21

· 2 pieces of Tipping bucket rain gauges

· 3 pieces of 3D sonic anemometers

· Air humidity, temperature and pressure sensors

· Video camera

· Ceilometer


· Mie scattering functions and cross sections for hydrometeors

· FSO link attenuation computation

Measurement Database

· 3 and1/2 year database of FSO link attenuation on our experimental link (830 as well as 1550 nm) synchronised with relevant meteorological parameters (visibility, rain rate, 3D wind parameters, beside this also refractivity and structure index from 6 month data)
