Targeting Laser
A laser designator is a laser light source which is used to Targeting (warfare), designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively. When a target is marked by a designator, the beam is invisible and does not shine continuously. Instead, a series of coded laser pulses, also called PRF codes (pulse repetition frequency), are fired at the target. These signals bounce off the target into the sky, where they are detected by the seeker on the laser-guided munition, which steers itself towards the centre of the reflected signal. Unless the people being targeted possess laser detection equipment or can hear aircraft overhead, it is extremely difficult for them to determine whether they are being marked. Laser designators work best in clear atmospheric conditions. Cloud cover, rain or smoke can make reliable designat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Designator- SOF In Afghanistan
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word "laser" is an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light which is ''coherent''. Spatial coherence allows a laser to be focused to a tight spot, enabling applications such as laser cutting and lithography. Spatial coherence also allows a laser beam to stay narrow over great distances (collimation), enabling applications such as laser pointers and lidar (light detection and ranging). Lasers can also have high temporal coherence, which allows them to emit light with a very narrow spectrum. Alternatively, temporal coherence can be used to produce ultrashort pulses of ...
