Principles of Operation

WASS is an optical-based system used to collect space-time data of sea surface elevations. It relies upon a pair of high-resolution digital cameras, which, once synchronized, allow the sea waves to be observed from two distinct points of view. With respect to the layout described in Benetazzo et al. (2012) and Benetazzo (2006), WASS has been improved to ease the installation and calibration phases, which are critical to get accurate measurements.
