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.
