Space distribution of Laser beam damping factors due to spray over whitecaps in a wave flume was measured by applying a new type of concentration meter, CT-type 2D Laser Concentration Meter, which can measure quasi-instantaneous concentration distribution in an arbitrary plane. The measured results pointed out a defect of this concentration meter caused by the virtual loading method employed by this meter; the evaluated damping factors near the edges of measured sections were lower than their real values. However, the results indicated some characteristics of spray distributions; the spray was highly concentrated besides the water surface in the vertical cross sections in initial stages where the fetch was short, and it distributed almost uniformly in the sections in the later stages, where the fetch was relatively long. This fact led to recognize the validity of this type of concentration meter when it's applied to the analysis of the spray over whitecaps
