The Lightweight Video Sight produced by Raytheon, the Mk 47's fire control system, utilizes the latest in laser rangefinding, I2 night vision and ballistic computer technology. In addition to being able to fire all NATO standard high-velocity 40mm rounds like the Mk 19 grenade launcher , it can fire MK285 smart grenades that can be programmed ...
The Pike is a precision-guided mini-missile [1] or grenade munition designed by Raytheon.It is a 40 mm guided munition that can be fired from the barrel of a Heckler & Koch M320 Grenade Launcher Module and FN Enhanced Grenade Launching Module (EGLM) like a standard 40mm grenade, but is powered by a rocket motor to propel it 2,000 m (2,200 yd; 1.2 mi) to give infantrymen improved extended-range ...
Alternatively, if a stable laser is available, the PDH technique can be used to stabilize and/or measure the instabilities in an optical cavity length. [3] The PDH technique responds to the frequency of laser emission independently of intensity, which is significant because many other methods that control laser frequency, such as a side-of ...
Fired 40 mm low-velocity M781 showing its orange signal chalk . 40×46 mm LV (low velocity) [2] is a NATO-standard [3] high–low grenade launcher cartridge meant for hand-held grenade launchers, such as the M79, M203, Milkor MGL, Heckler & Koch AG36 and M320 Grenade Launcher Module.
Etalon-1 and Etalon-2 are geodetic satellites. They are designed to determine, with high accuracy, terrestrial reference frame and Earth rotation parameters, to improve the gravity field, and to improve the gravitational constant. Each satellite is a high-density passive laser reflector in a very stable medium Earth orbit (MEO). [3]
The LG5/QLU-11 can be equipped with free-floating barrel, a fire-control system with a laser rangefinder, thermal imaging capability, and a ballistic computer that gives it air burst capability. [ 3 ] [ 6 ] The QLU-11 was tested in combat against Somali pirates in the Gulf of Aden by Chinese marines . [ 7 ]
Interference fringes, showing fine structure, from a Fabry–Pérot etalon. The source is a cooled deuterium lamp. In optics, a Fabry–Pérot interferometer (FPI) or etalon is an optical cavity made from two parallel reflecting surfaces (i.e.: thin mirrors). Optical waves can pass through the optical cavity only when they are in resonance with it.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
