| | Though an optical link propagates in empty space in an easily foreseeable way, the atmospheric path proves to be more difficult, because of both atmospheric turbulence and the turbulence generated by the aircraft itself, at the level of the window.... We should stress the role played by the " PILOT " computing code, the acronym stands for Propagation and Imaging, Laser and Optics, through atmospheric Turbulence, one of Onera team's simulation codes that capitalizes on a whole unique body of know-how developed for the needs of high resolution imaging (adaptive optics...) in particular.... |
