Laser-based missile defense for helicopters being developed

ANN ARBOR, Mich.---Protecting helicopters in combat from heat-seeking missiles is the goal of new laser technology created at the University of Michigan and Omni Sciences, Inc., which is a U-M spin-off company. "Battlefield terrain in places like A...

Planet-Hunting Machine is Getting Even Better

The world's best planet-hunting machine, the Keck High Resolution Echelle Spectrometer, will be getting even better this year with an advanced imaging array that will improve efforts to detect extra-solar planets, examine distant quasars, measure extragalactic stars and do other research requiring very precise wavelength measurements of thousands of color channels with one exposure. HIRES, a visible-wavelength spectrometer responsible for 20 percent of the science on the Keck I telescope, will be getting an advanced new detector that will increase photon detection rates at ultraviolet wavelengths by a factor of 8 (at 3200 ?), expand single-exposure wavelength coverage, provide finer sampling of spectral features, and allow faster readout rates to provide higher-quality science in less time.
