Optical Direction-Finding Based on Silicon Photonic Integrated Circuits

In this paper, a high accuracy direction-finding (DF) system based on silicon photonic integrated circuits (PIC) is proposed. The accurate direction of a target can be determined by its position in the reconstructed image obtained by spatial frequency (SF) sampling and inverse Fourier transform acco...
