The correction of dynamic aero-optical aberration of optical dome at different altitudes using wavefront coding

Abstract

In our previous published paper [Opt. Commun. 490, 126876 (2021)], we proposed a method to correct the optical dome’s aero-optical aberration using wavefront coding (WFC). The simulation results were carried out under a fixed flight altitude. However, because the missile tracking the target is a dynamic process, the image quality deterioration of the aero-dynamically heated dome is diverse under different altitude. Therefore, it is of great significance to study the correction effect of WFC on dynamic aero-optical aberration of optical dome at different altitudes, which is performed in our new manuscript. The simulation results demonstrate that the WFC could effectively correct the dynamic aero-optical aberration and improve the accuracy of imaging guidance. These results confirm the possibility of the application of WFC imaging technology in missile-borne optical detection systems.
