The Fédération Internationale de Tir aux Armes Sportives de Chasse (FITASC) Compak Sporting is a type of shotgun sport shooting similar to sporting clays, trap and skeet. Other shotgun sports with (at least partial) international recognition include Sporting Clays, Down-The-Line /ATA and Five stand. Trap shooting in USA.
A laser designator is a laser light source which is used to 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 ...
The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [ 1 ][ 2 ] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.
A hardpoint is an attachment location on a structural frame designed to transfer force and carry an external or internal load.The term is usually used to refer to the mounting points (more formally known as a weapon station or station) on the airframe of military aircraft that carry weapons (e.g. gun pods and rocket pods), ordnances (bombs and missiles) and support equipments (e.g. flares and ...
In a rotating ring laser gyroscope, the two counter-propagating waves are slightly shifted in frequency and an interference pattern is observed, which is used to determine the rotational speed. The response to a rotation is a frequency difference between the two beams, which is proportional [ 1 ] to the rotation rate of the ring laser ( Sagnac ...
A telescopic sight, commonly called a scope informally, is an optical sighting device based on a refracting telescope. [1] It is equipped with some form of a referencing pattern – known as a reticle – mounted in a focally appropriate position in its optical system to provide an accurate point of aim.
A waveplate mounted in a rotary mount. A waveplate works by shifting the phase between two perpendicular polarization components of the light wave. A typical waveplate is simply a birefringent crystal with a carefully chosen orientation and thickness. The crystal is cut into a plate, with the orientation of the cut chosen so that the optic axis ...
The recorded light pattern is a diffraction grating, which is a structure with a repeating pattern. A simple example is a metal plate with slits cut at regular intervals. A light wave that is incident on a grating is split into several waves; the direction of these diffracted waves is determined by the grating spacing and the wavelength of the ...
