Abstract
The performance of free-space optical communication links is impaired by atmospheric effects such as optical turbulence. Several techniques are being investigated for emulating the effects of turbulence in the laboratory. Here we explore the use of an optical turbulence generator, facilitating the investigation of turbulent effects and the development and evaluation of mitigation strategies. In this work, the design of a hot-air-based optical turbulence generator is discussed. The characterisation is performed using an off-axis digital holography measurement setup, allowing measurements of the perturbed complex optical field. The measured data can be further analysed in the digital domain. The results of an experimental investigation of mode diversity reception, a technique to improve free-space-to-fibre coupling, are presented.
