Abstract

A new method of high resolution laser imaging is developed in this paper, which is denoted as Fresnel telescopy. It creates Fresnel zone plate (FZP) fringe at the detected target, then makes relative motion between Fresnel zone plate and the target to accomplish the encoding process, namely, to achieve the convolution between target reflection function and the Fresnel zone plate intensity distribution function. The design scheme of the proposed system is presented. The proposed technique offers significant practical benefit for ground-based imaging of objects in many important military applications.
