چکیده انگلیسی
In order to improve the dynamic state resolution of aerial remote sensor, it is indispensable to analyzing image rotation of aerial remote sensor. According to optical reflection vector theory, study on imaging character of aerial remote sensor with off-axis three-reflective optical system. At first, a simple mathematics model is abstracted from the aerial remote sensor. In the Cartesian coordinate system, compute the image plane revolution vector quantity caused by scan mirror rotating of parallactic angle and depression angle by analysis of image rotation direction for aerial remote sensor with off-axis three-reflective optical system applying coordinate conversion and geometrical optics, provide a theoretical resource for the application of the drift mechanism (eliminating image rotation mechanism). Using this method can calculate exactly image motion and image motion compensation error of image planeand image motion quantity less than 0.003Â mm. In conclusion, the result of the computation improves Modulation Transfer Function (MTF) of optical system.
