Abstract:

	A need has been identified for an electronic still camera for space flight applications
that incorporates a suitable solid-state electronic imaging detector. In this project,
the key performance specifications concerning the detector--including optical sensitivity,
spatial resolution, readout rate, dynamic range, dark current, and spatial crosstalk--will
be identified. A number of experiments and tests will be performed to determine the
optimal combination of charge-coupled-device (CCD) and CCD readout and signal processing
technologies to produce a detector suited for electronic still photography applications.
These include evaluation of CCD transport register architectures and approaches to
increasing sensitivity to blue/visible wavelengths; testing noise and noise spectral
characteristics of various output amplifier design approaches; evaluations of high-speed
CCD double-correlated signal processing circuits; and evaluation of the feasibility
of employing multiple CCD output ports.
