The Field Camera Unit

This report provides an overview of the results from the Field Camera Unit (FCU) technical meeting, including the definition of scientific objectives, top-level requirements, and trade-off processes for optics, mechanics, and electronics solutions. It also covers the identification of critical elements, feasibility assessment, and costs.
