| 中文摘要: |
| 为了对特定微结构时间延迟积分电荷耦合器件（TDICCD）相机进行装调及性能测试，提出并搭建了一套动态调制传递函数（ MTF ）地面模拟测试装置。在实现TDICCD相机成像的基础上，利用刃边法对相机的MTF进行测量。经理论分析及实验验证，该装置测量精度优于5%，满足设计要求。并利用该装置分析了速高比v/h、偏流角$ \theta $这两个因素对TDICCD相机像质的影响，其结果与理论相符。所提出的装置满足TDICCD相机地面动态MTF测试技术需求，具有一定工程意义。 |

| In order to assemble and test a microstructure TDICCD camera, a dynamic MTF test device was proposed and built. The MTF of the camera is measured by the edge method. After theoretical analysis and experimental verification, the measurement accuracy of the device is better than 5%, which meets the design requirements. The device is used to analyze the influence of the two factors of speed-to-height ratio and drift angle on the image quality of TDICCD camera, and the results are consistent with the theory. The construction of this device satisfies the requirements of the ground dynamic MTF test of the TDICCD camera, and has certain engineering significance. |
