WASHINGTON — NASA is investigating a detector problem common to three primary instruments on the James Webb Space Telescope (JWST) that could get worse with time as a planned 2014 launch date for the ...

The world of laser scanning microscopy is quickly evolving, thanks to the advent of fast and compact detector arrays. These arrays replace the typical single-element detector of traditional confocal ...

Mid-infrared (IR) array detectors have been used for astronomical observations in space. However, the uniformities of their spectral response curves have not been investigated in detail, the ...

THE DESIRE TO DETECT ever fewer photons and ions, including some at great distances from Earth, pushes the frontiers of analytical capability. A symposium at Pittcon in Chicago earlier this month ...

a, Example of ISM-FLUX on nanorulers consisting of three fluorophores with 40 nm spacing between nearest neighbours. With a single-element detector, none of the nanorulers can be resolved, due to the ...
