Journal ArticleDOI
Registration of motion-distorted interlaced images captured by a scanning vector imaging sensor.
TL;DR: An algorithm to realign images distorted by motion and vibrations captured in cameras that use a scanning vector sensor with an interlaced scheme is presented and has a computation advantage over algorithms based on the technique of searching for a match.
Journal ArticleDOI
Relative effects of distortion and noise on target acquisition: the advisability of image restoration
TL;DR: This work characterize the influence of the MTF and noise level on human target acquisition probability to ascertain the advantages, if any, of image restoration.
Proceedings ArticleDOI
Aerosol MTF revisited
TL;DR: In this article, the authors present clear experimental evidence of common significant aerosol blur and evidence that aerosol contrast reduction can be extremely significant, and the role of imaging system instrumentation on such MTF is addressed too.
Journal ArticleDOI
Ultraviolet photoconductive detectors in Zn3P2
TL;DR: In this article, photoconductive detectors with relatively flat response to wavelengths as short as 2500 A have been fabricated in thin films of zinc phosphide deposited by the close-space-transport method on to mica substrates.
Journal ArticleDOI
Spectral Dependence of Rise Time in Gas Filled Phototubes: Implications concerning Possible Miniaturization of Gas Discharge Detectors of Electromagnetic Radiation
G. Eytan,Norman S. Kopeika +1 more
TL;DR: In this paper, the rise time of a gas-filled photodiode at blue-green wavelengths is found to be less than that at red wavelengths, and it is suggested that these phenomena decrease parasitic inductance of the tube.
