The detectors are "orthogonal transfer" CCDs (OTCCDs), invented by John Tonry and others at the University of Hawaii's Institute for Astronomy and MIT's Lincoln Laboratory.
MIT's device, dubbed OTCCD for orthogonal transfer CCD, allows the charge to move in perpendicular directions, and to do so repeatedly before an exposure ends.
A prototype OTCCD was tested on the Michigan-Dartmouth-MIT 2.4-meter reflector in Arizona, where it reduced the diameter of star images from about 3/4 to 1/2 arcsecond.
