Design and simulation of a high resolution active imaging technique utilizing Fresnel telescopy

A new technique for high resolution active laser imaging of space objects is demonstrated. The technique, referred as Fresnel telescopy, is a variant of Fourier telescopy, which additionally uses Fresnel zone plates to scan objects. The design scheme of a compact schematic of transmitting and receiving system for Fresnel telescopy is proposed. We provide simulations results for imaging of a photograph of satellite to illustrate and clarify the proposed idea. The technique is found to have substantial practical value and offers significant practical benefit for high resolution imaging of objects in the field of military applications.
