Lessons from the Battlefield: Technology Transfer Cuts Both Ways
As an industry, photonics can testify to the value of technology transferred out of the military. Charge-coupled devices, diode lasers and infrared imaging all owe much of their early development to...
(Emerging Technologies) Lasers:
Industrial and consumer applications in abrasives and machine tooling have used man-made diamond -- the hardest known material -- for more than 40 years. More recent research using lasers to create...
Fiber Optics Finds a Limit
Several optical effects can degrade the signal quality of optical transmission over silica glass fiber. The more well-known mechanisms, such as attenuation and chromatic dispersion, are linear in...
A Light-Speed Defense Against Mach-Speed Missiles
The proliferation of short- and long-range missiles did not end, as some hoped, with the Cold War. As Iraq and North Korea have illustrated, modern missile technology can lend first-class military...
