ISIIS Technology / Capabilities

ISIIS instruments utilize a Patent Pending technology that uses line scan cameras from the machine vision industry to scan the water and provide a continuous imaging with 60 micron pixel at 4-5knots speed. The line scan camera is coupled with a back illumination technique (shadowgraph) that provides exceptional resolution and depth of field while providing a telecentric image (magnification is not affected by distance from object to lens). The data is either ported to shipboard via Fiber-optic towing cable or recorded internally.

ISIIS instruments are designed to image large volume of water in order to study relatively rare organisms (fish larvae). The vehicles and its imaging system are configurable and give the versatility needed for studying a range of organism - from small, abundant plankton, to larger and more rare specimens. Moreover, analysis results show the instruments are able to adequately quantify densities of fish larvae.
