Abstract
In order to study effects of outdoor factors to Fourier telescopy imaging and validate properties of imaging immune to down-link atmospheric turbulence,outdoor experiments were developed.Under the ground of lab experiments,outdoor experiments added primary mirror,secondary mirror and condense lens to simulate the real system imaging.The distance between object and primary mirror and the distance between primary mirror and secondary mirror was put away 100m,separately,to validate the property of Fourier telescopy imaging immune to atmospheric turbulence.Using 2 different satellite films as objects,the outdoor reconstructed images were gotten with the Strehl value 0.44 and 0.39 without turbulence,separately,and Strehl value 0.43 and 0.38 with turbulence,separately.Compared the reconstructed images of outdoor with lab,the conclusion was gained that libration had obvious effect on imaging.The result that the Strehl value of outdoor imaging was similar to lab imaging confirmed the fact that Fourier telescopy imaging was immune to down-link atmospheric turbulence.
