Abstract

Nowadays the remote sensing instruments require relatively larger FOV and higher LOS pointing accuracy. However, the traditional scanning model can only have a relatively small scanning area. As the scanning area increases, the image rotation will increase rapidly. The traditional two-dimensional scanning model has failed to meet the growing demands of remote sensing instruments. To solve the problem, in this paper, the differences of all kinds of two-dimensional scanning method are analyzed and compared, and different ways to place and rotate two-dimensional scanning mirror are also considered. Finally, through analysis, a kind of two-dimensional scanning model which meets the large area two-dimensional scanning requirements was obtained. At the same time, the image rotation of large area two-dimensional scanning model is analyzed, which provides data support for image processing.
