A compact, two-dimensional scanning laser slope gauge has been developed for measuring ocean ripples, leading to the determination of their directional slope spectrum in the wavelength range of 4.5-81 mm. A telecentric scanning mechanism is used to enhance the dynamic range of slope measurements and to eliminate constraints caused by water-surface undulations associated with long waves. Successful laboratory tests and field trials have been performed; sample results are provided.
已开发出一种紧凑的二维扫描激光倾斜仪，用于测量海洋波纹，从而确定其在4.5-81毫米波长范围内的方向斜率谱。采用远心扫描机制来提高斜率测量的动态范围，并消除与长波相关的水面波动所造成的限制。已成功进行了实验室测试和现场试验；并提供了样本结果。
