[ABSTRACT] Every ship determines its cruse course by taking into account the state of sea waves due to weather conditions. In the viewpoints of fuel efficiency, safe sailing, vibration damping, and automatic steering, it is useful for the captain to obtain a motion of forward waves. Sea save is greatly affected by not only flow and depth of seawater, but also temporal wind blowing on the sea surface. To observe wave sea dynamics, we developed a LED based mini-lidar and the high-speed photon counter to catch the target motion of 0.1-1Hz. The power LED of 0.75W@385nm was utilized. Its divergence is 10mrad, while the receiver's field of view is <5mrad. This setup is eye-safe and robustness for rough treatment. The pulse frequency was 500kHz and the spatial resolution was 0.15m. The ground experiment was conducted at a coast with shallow angle. The sea wave dynamics was captured at every 0.25s.
