海浪谱的光学探测及信息处理

Optical Detecting and Processing of Seawave Spectrum

建立了一套光学——计算机混合处理系统用以分析海浪航空底片,并得到了海浪方向谱和能谱。实验结果与现有的海浪理论符合较好,同时显示了该方法有可能发展成一种实用的实时海浪探测方法。

In this paper,a hybrid Optical-Digital processor is set up to analyse aerial seaphotographs,and the directional seawave spectrum and power spectrum are obtained using theprocessor.The experiment results agree with the seawave theory well and show that the processorand processing method can become one of the practical method to analyse seawave spectrum inreal time.
