摘　　要：通过对特定视场条件下扫描型288×4红外热成像系统的扫描成像过程的分析,提出了以水平方向图像分辨率为基础的动态瞬时视场概念,并以此为出发点,建立了扫描成像过程中扫描电机正程速率与探测器积分时间的数学关系式,提出了在保证电机的扫描线性度和扫描效率条件下,实现288x4热像仪行扫描速度与探测器积分时间的调整和配合的指导性意见。By analyzing the scan imaging process of IR Imaging system based on 288 × 4 IRFPA in a special FOV（Field of View）, a concept named dynamic instant field of view（IFOV） is given out based on the image horizontal resolution. And based on this concept, a mathematical relationship is established between the swing speed of the scanner and the integration time（INT） of IR Detector, some suggestions are given on how to make regulation between the IR Imager swing speed and the integrate time of IRFPA when the linearity and the efficiency of scanner is confirmed.
