摘要

A new infrared laser-glint sensor is being developed to measure sea-surface roughness statistics, using a CO$-2$/ laser to maintain the laser signal above background light levels. This new system allows daylight data collection, whereas our previous HeNe-laser-based system operated only at night. Additionally, the new system incorporates real-time correction of ship motion to allow operation on a moving ship. This paper provides an overview of the instrument design and the scientific objectives of its future deployment. A specific scientific objective discussed here is determining the connection between the fractal dimension of the laser-glint process and surface roughness. Evidence is shown here from previously acquired laser-glint data that the laser-glint- count process is fractal, with a dimension that appears to vary with surface roughness. Plans are outlined for deployment of the new laser-glint sensor with fractal signal processing for remotely sensing surface roughness.
