摘要: 鉴于水的吸收和散射效应，用普通光源进行水下探测一直以来都非常困难，利用激光的光谱特性和时间特性，可以有效减少水对光的吸收和散射效应。为了验证激光光源进行水下探测的可行性，利用He-Ne激光作为光源，分别对空气和水中物体的反射系数进行了测量，并与参考数据作了比较，实验效果良好。通过数据分析比较可以确定该物体的类别，最后对其应用作了展望。

Abstract: Because of the absorption and scattering effect of water, it is always very difficult to explore under water with common light source. With advantages of the characteristics of laser, the absorption and scattering effect of water is reduced. Taking He-Ne laser as the light source, the reflection coefficients of the objects were detected in the air and underwater to make sure the feasibility of underwater exploration with laser. It is found that the experiment result is good after comparing the detected results with the reference data.
