摘　　要：详细介绍了微扫描的原理,在对微扫描成像性能的评价过程中引入了像素传递函数的概念,并给出了在微扫描模式不同时的探测器阵列的像素传递函数及其曲线,给出了微扫描模式不同时的微扫描重建图像。通过理论和计算机仿真分析可知,微扫描能有效地减小频谱混淆,提高图像分辨率。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.
