Abstract:
This project will develop a back-illuminated image sensor
based on charge-coupled-device (CCD) technology with improved
stable quantum efficiency in the ultraviolet as well as the
visible spectrum. The CCD will also have high quantum efficiency
in the soft x-ray region and be useful in electron bombarded
applications. The high quantum efficiency that can be attained
with this back-illuminated CCD, combined with the very low readout
noise at wide bandwidth, makes it possible for this CCD to replace
image intensifier-CCD image sensors currently used for night
vision and low light surveillance applications. Unlike other
cameras, the CCD sensor is small and reliable, has a longer life
and broader spectral response, and, therefore, has significant
commercial and NASA applications.
Potential Commercial Application:
Potential Commercial Applications: The CCD image sensor can be
used in NASA astronomical missions, ground-based scientific
imaging instruments, and for low-light surveillance cameras in law
enforcement and industrial applications.
