Navigating by light
Article Abstract:
Ring laser and fiber-optic gyroscopes replacing traditional mechanical gyroscopes. This technology has military applications as it has improved the accuracy of navigation and weapon aiming systems. Ring laser gyros are structured as a laser enclosed in a ring-shaped conduit inside a monolithic solid glass block. The laser's optical path is either triangular or square which is filled with a helium/neon gas medium. This technology is now preferred by military technicians because it is able to withstand mechanical shock without degradation of its performance.

Casting light on target
Article Abstract:
Laser radars have emerged as another viable method for battlefield target detection to support use of the laser rangefinder. Unlike traditional radars that illuminate targets with radio-frequency energy through a magnetron or travelling wave tube, these radar systems apply laser light to detect targets. Operating modes for laser radars include differential absorption light detection and ranging systems and coherent heterodyne detection systems.

Telling friend from foe
Article Abstract:
The increasing demand for minimal or no casualties in military warfare has led to improvements in Identification Friend or Foe (IFF) systems. Traditional IFF systems were first used for air defense. Increasing military requirements have moved manufacturers to create systems that would be similarly effective for ground combat. Although IFF systems face the possibility of output failure, they are still useful for effective combat.
