| 中文摘要 | Mechanical vibration is the main source limiting and damaging the resolution of aerial cameras. It is necessary to stabilize the line of sight (LOS) to guarantee the image quality. Using dynamic MTF to evaluate image quality and establish reasonable stabilization system performance standard, is a common artifice during the design process. Linear motion and high frequency vibration MTF have been expressed in closed form; however, low frequency vibration still cannot be solved analytically. A numerical dynamic MTF calculation method was developed. With this method and corresponding results, the image quality as well as affordable residual vibration under particular oscillations can be predicted. As a result, passive isolators and other image system devices can be selected effectively and properly. |
