Abstract
In this paper, a diffractive optical element (DOE) is adopted to control the side lobe to be extremely low in a large region on the focal plane, and simultaneously the intensity of the center point on the focal plane is required to be maximal. The DOE to realize the before-mentioned performance is two-phase distributed, i.e. 0 and Ï. Linear programming is applied to design the DOEs to realize an extremely low side lobe in different regions on the focal plane. Simulated results show that the more rigorous the side lobe is controlled to be, the smaller the intensity of the center point on the focal plane.
