WAVEEHEIGHT MEASURING SYSTEM BY LASER RAY

摘要: PURPOSE:To measure the wave height of surface water located at a long distance from fixed point on ground, etc. without providing navigation shipping with obstacles, by irradiating laser rays sea or rivers, and obtaining information thrown-back reflections gained. CONSTITUTION:When keeping spread angles beams constant, numbers stripes 2' are comparatively few as striped patterns 6-1 when is high because waves observed irradiated formed line beltlike about one mount arranging in row- like shapes. When low, contrary, become more 6-2. Meanwhile, relationship between length area to be measured beforehand obtained using wind velocity, direction, tides, parameters has strong element related characterized regional groups. Thus, can gained measuring an image-formation plate 6 moving directions.
