In order to verify the validity of Fourier telescope technology,the experimental demonstrations were carried out in a lab.The time-modulated return signals containing Fourier information were obtained by scanning object with different space frequency fringes.Then,the object spectra were captured with Fourier demodulated and phase closure techniques,and the constructive images were obtained by two-dimensional inverse Fourier transform.Finally,the constructive images of 3mm object were obtained in a lab.Compared with the computer simulation,the experimental results demonstrate that Fourier telescope imaging in the lab agrees well with the computer simulation,these results will be important references for later lab experiments and field experiments.
