In order to make the simulation of the Fourier telescope imaging system close to reality, the structure of field experimental system is improved. Reflected objects are used, space filters and collimation lenses are replaced by collimation beam-expanders, and large sensitive area charge coupled device is used to monitor imaging. For different cases without atmosphere and with 200 m level atmosphere, 4 objects with different spatial spectra are researched. 9×9, 17×17, 33×33 and 65×65 Fourier components are used for reconstruction. The best angular resolution of imaging is 3.5″. The results indicate that the Strehl ratios of reconstructed images with 200 m level atmosphere are close to those without atmosphere, and then prove that the Fourier telescope imaging system is immune to effects of low-order atmospheric turbulence.
