Jin Kang, an associate professor in Johns Hopkins' electrical and
computer engineering department, is helping NASA's Goddard Space Flight Center
lighten the load of an upcoming launch in 2003. Kang is creating an ultraviolet
light source based on fiber-optic technology that reduces the weight of NASA's
LIDAR system, a variation of radar that uses light instead of radio waves.
"Suppose you wanted to monitor a hurricane from space," says Kang.
"Using a UV laser would require a huge power supply, which would be too heavy.
The laser I'm developing is unique because it uses power very efficiently and
doesn't require a weighty power supply."
Kang's laser is a component in NASA's LIDAR system. The system
aims light beams at the Earth's atmosphere. The return signal carries back a
wavelength absorption fingerprint that is used for identifying gases in the
atmosphere and their densities.
For more information about the fiber-optic technology, contact
Kang at (410) 516-8186 or email@example.com. The
address for Johns Hopkins University is 3003 N Charles St., Baltimore, MD 21218.
