New Laser, Set of Eyes for Military: Engineers
Engineers have discovered a new laser that could be proved as a breakthrough in military empowerment.
Military aircrafts can be equipped with new laser to identify arsenals and hidden dangers, said Mohammed Islam, a professor of electrical engineering and computer science and biomedical engineering at the University of Michigan. He referred it as a new set of eyes for the defense and intelligence communities.
Off-the-shelf telecommunications technology has been used by the engineers to build the system. A broadband beam of infrared light is emitted by the system. Unlike most lasers, it emits light of range of wavelengths with a blend of colors. The beam is invisible to human eyes as it is in the infrared region. It can, however, illuminate deep information.
"A grey structure looks grey in visible light, but in the infrared, you can see not only the shape, but also what's inside it", Islam said.
The infrared contains "spectral fingerprinting range". It is frequencies at which it becomes easy to detect echoes of the vibrations of the molecules that build a solid space.
He added high-power lasers could strengthen the aircrafts to illuminate a region with brightness comparable to sunlight, despite flying at higher altitudes.
