Abstract: Abstract:Water surface fluctuations were analyzed using image sequences from a CCD (charge coupled device) camera. Both regular and irregular waves were used for the study. A transfer function is obtained by comparing the gray scales of the image and results of in-situ wave gauge array measurements. The effects of non-uniform illumination within the wave basin are imbedded in the transfer function. Thus, the obtained transfer function is directly applicable to all other areas of interests within the wave basin. Estimated wave heights are all in qualitative agreement with those obtained through direct measurements. It is shown that the averaged relative error between these two wave heights is less than 16%.
