Spatial Coherence Degradation of Light Influenced by Temperature and Aerosol by Use of Atmospheric Turbulence Chamber

The spatial coherence of light influenced by temperature and aerosol is measured. An atmospheric turbulence chamber is used in experiments. The spatial coherence of light degrades with increase of turbulence in accordance with the rise of temperature and the increase of aerosol. In the experiment for wavelength dependency, the degradation is larger for a shorter wavelength. The experimental results are in good agreement with theoretical results currently available.
