海水水体的点扩展函数(PSF)及光学传递函数(OTF)描述了海水中光或图像传输的性质，是研究海水光学性质及水下图像系统的基本参数。探讨了用图像传输的理论测量海水点扩展函数或光学传递函数的方法，在实验室中建立了一套测量和计算系统；对不同长度的散射水体进行了测量，得到了一维和二维的海水点扩展函数曲线，测量结果与理论分析相符合。

A laboratory facility to measure and calculate the point spread function (PSF) and the optic transfer function (OTF) of seawater is described. The PSF and OTF are important parameters for predicting light propagation and imaging system performance. An image transmission method for measuring the PSF is discussed and the 1-D and 2-D PSF curves for various scattering water path lengths are presented. The OTF are also calculated by FFT from the data of PSF. Some results are shown, which agree with the theory.
