Simulation of Angle-of-Arrival fluctuations as observed in the MISOLFA pupil plan

International audienceThe MISOLFA seeing monitor is developed to analyze spatial and temporal statistical properties of daytime optical turbulence. It is based on Angle-of-Arrival (AA) statistical properties. The MISOLFA optical device measures AA-fluctuations observed as intensity variations in the pupil plane image formed through a thin slit positioned in the instrument focal plane on the solar edge. Numerical simulations are then performed to ensure the system performances. We present here its basic principles and some obtained results
