مقاله Achieving sub electron noise in CCD systems by means of digital filtering techniques that lower 1/f pixel correlated noise : تی پی بین

خلاصه مقاله

Scientific CCDs designed in thick high resistivity silicon (Si) are excellent detectors for astronomy, high energy and nuclear physics, and instrumentation. Many applications can benefit from CCDs ultra low noise readout systems. The present work shows how sub electron noise CCD images can be achieved using digital signal processing techniques. These techniques allow 0.4 electrons of noise at readout bandwidths of up to 10 Kpixels per second while keeping the full CCD spatial resolution and signal dynamic range.

Experimental Astronomy 2013

Many new instruments for observing astronomical objects at a variety of wavelengths have been and are continually being developed. Consequently, a vast amount of effort is being put into new data analysis techniques to cope with rivers of data collected by these instruments.Experimental Astronomy is a medium for the publication of papers of contemporary scientific interest on astrophysical instrumentation and methods necessary for the conduct of astronomy at all wavelength fields.Experimental Astronomy publishes full-length articles, research letters and reviews on developments in detection techniques, instruments, and data analysis and image processing techniques. Occasional special issues are published, giving an in-depth presentation of the instrumentation and/or analysis connected with specific projects, such as satellite experiments or ground-based telescopes, or of specialized techniques.Commonly used title abbreviations: Exp. Astron., Exp Astron, ExA
