摘　　要：讨论了基于288×4探测器热像仪外同步功能的局限,提出了一种将热像仪扫描采样流程与视频输出流程在时序上"脱钩"的办法,使热像仪能够与存在误差的外同步信号同步,该方法已在某扫描型热像仪上得到了实现。This paper discusses the limitation of external synchronization in thermal imager based on 288 ×4 detector, and develops a solution to make thermal imager synchronized with an external sync signal which has an uncertain sync error. This solution decouples the procedure of scanning and sampling from the procedure of video output, which has been achieved in some scanning thermal imager already.
