Project Overview:

A new edition of the SPC was commissioned by Francesco Pomati of Eawag, the Swiss Federal Institute of Aquatic Science and Technology. The SPC-DUAL combines both the 5x and 0.5x magnifications of the SPC and SPCP into one pair of housings. A second SPC-DUAL was built concurrently with the first for use at Scripps. It is shown above attached to a Wirewalker for a pilot study of a profiling deployment.

General Information:

The system is built around a pair of Matrix Vision 12 MP USB 3.0 industrial cameras. Both cameras are controlled by an Nvidia Jetson TX1 single board computer that allows up to 20 fps with roi detection in real time, and support circuitry allows for integration and powering of external sensors and accessories. Additionally, an internal battery pack allows for independent operation.
