| Abstract: | In this paper theory of micro scanning is described in details. The concept of pixel transfer function is introduced in performance evaluation of micro scanning imaging and the pixel transfer functions and its curves of detector array with different micro scanning mode are presen- ted. The reconstructed images with different micro scanning mode are presented as well. The re- suits show the technique of micro scanning can effectively reduce the spectrum aliasing effect and improve the final image resolution. |
