UTOFIA offers a compact and cost-effective underwater imaging system for turbid environments. Using range-gated imaging, the system extends the imaging range over conventional video systems and provides video-rate 3D images.

This fills the current gap between short-range, high-resolution conventional video and long-range low-resolution sonar systems. UTOFIA offers a new modus operandi for the main targeted domains of application: marine life monitoring, harbor and ocean litter detection, fisheries and aquaculture stock assessment, and seabed mapping.

SINTEF provided technical and administrative leadership for the project, and also had the main responsibility for the built-in signal processing.
