| 摘 要： | 由YAG激光发生器产生的二次谐波诱导的自然树叶的荧光图像可由具有快门控制和图像增强装置的像机远距离直接探测到，利用彩色滤光片的分光可说明荧光是由树叶的叶绿素引起的，叶绿素可用来区别树木和其它物体。150m范围内的树木位置可由荧光图像确定。结果表明，这种技术在植物分布监测中有很大的应用潜力。

| Abstract: | Fluorescence images of natural tree leaves induced by the second harmonic of a Q-switched YAG laser have been remotely and directly detected by a lidar with a gated image-intensified charge-coupled-device(CCD)camera. Simple spectroscopic measurements using a colored glass filter showed that the fluorescence was caused by the chlorophyll in the leaves. The chlorophyll fluorescence was useful to distinguish trees and other objects. Tree location up to a distance of around 150 m from the system were also determined with a range resolution of 15m from the range-resolved fluorescence images. The results showed that this technique has a great potential use as a monitor of vegetation distribution. |
