| 摘 要： | 讨论了用调制传递函数（ＭＴＦ）表征水下激光成像质量特性及其影响因素的量值关系，给出了计算该系统ＭＴＦ的理论近似公式，得出了ＭＴＦ与激光束光斑的大小，目标的距离，接收视场角及光功率的数量关系，结果表明准直光斑的减少和采用窄视场的扫描技术能有效地提高成像的分辨率。

| Abstract: | The quantity relationship that is expressed the character about imaging quality of underwater laser and affected factors by mondulation transfer function (MTF) is discussed. The approximately theoretical formula calculated for this system is given. The quantity relationship between (MTF) and facula, distance of target, received view angle, light power is derived. The results show that imaging resolution can be efefectively improved by collimating laser facula, and using synchronous scanning technology of narrow view. |
