title = "Lightweight diffractive telescope",
abstract = "In order to collect detail information of the object in dim, the telescope image system need to be high-resolution and can gather enough power. These requires telescope image system with a large-diameter. Considering the load ability of the aircraft, there is also a strong demand for miniaturization and lightweight of the telescope system. Diffractive optical elements (DOEs) have great advantages in meeting these requirements. We designed two sets of telescope image systems with the same technical specifications. The primary mirrors of the two systems use traditional refractive lenses and DOEs respectively. By comparing the traditional refractive lenses and DOEs under the same focus and diameter, we demonstrate that DOEs have obvious advantages when it be applied in airborne optical systems with high requirements on volume and weight.",
