  World Space Observatory UltraViolet (WSO-UV) is a multipurpose space
observatory, made by a 170 cm aperture telescope, capable of UV high-resolution
spectroscopy, long slit low-resolution spectroscopy, and deep UV and optical
imaging. With a nominal mission life time of 5 years, and a planned extension
to 10 years, from a geosynchronous orbit with an inclination of 51.8 degrees,
WSO-UV will provide observations of exceptional importance for the study of
many unsolved astrophysical problems. WSO-UV is implemented in the framework of
a collaboration between Russia (chair), China, Germany, Italy, Spain, and
Ukraine. This book illustrates the results of the feasibility study for the
Field Camera Unit (FCU), a multi-spectral radial instrument on the focal plane
of WSO-UV. The book provides an overview of the key science topics that are
drivers to the participation of the Italian astronomical community in the
WSO-UV project. The science drivers here illustrated have been used to define
the technical requirements for the conceptual and architectural design of the
Field Camera Unit (FCU) focal plane instrument. In Chapter I we show that
WSO-UV will give a significant contribution to solve the key astronomical
problems individuated by the ASTRONET consortium, and which are driving the
European Space Agency Cosmic Vision program. Chapter II elucidates the
scientific requirements for WSO-UV FCU instrument, discussed in Chapter I,
which are translated in a list of verifiable top level requirements usable to
make the conceptual design of the FCU instrument. Chapter III is dedicated to
the Field Camera Unit opto-mechanical design, its detectors and electronics
subsystems. Finally, Chapter IV outlines the AIV and GSE plans and activities
for the FCU instrument.
