Analysis of Influence of the Spectral Channels of AWG on the Imaging Quality of Planar Interferometric Imaging System

The Planar Interferometric Imaging System samples the object visibility in the Fourier domain and then digitally reconstructs an image. Firstly, the principle of SPIDER imaging is studied, the principle of AWG is analyzed, and the influence of different bandwidth on the visibility of interference fringes is simulated. The results show that increasing the number of spectral channels of AWG can improve the visibility of interference fringes, effectively increase the spatial frequency coverage and improve the imaging quality.
