New drift adjusting method of space camera

At present, there are some conditions in the research field of the space camera. For example, the imaging mode is single of the optical imaging reconnaissance satellite in our country. The detection efficiency of the satellite is very low for banded target curve. Therefore, it need to carry out a research about the new drift adjusting method of the space camera. This research requires a basis that is the real time compensation technology for the image motion of the camera. First, the theory of the new drift adjusting method of the space camera was introduced, and a drift adjusting mechanism was designed. This mechanism can make the space camera with the real time compensation technology for the image motion. At present, the traditional drift adjusting method is that making all of the TDI-CCDs which have been assembled running together. Know from this, the new drift adjusting method make the TDI-CCD running singly to achieve the time compensation. At last, the transmission accuracy of the flow deviation was analyzed and tested. The test results show that there are many advantages of the drift adjusting mechanism which designed in this article, such as the transmission accuracy is high, and the response speed of structure system is quickly. With this drift mechanism, the space camera can complete the agile imaging reconnaissance tasks.
