This is a list of United States Army fire control, and sighting material by supply catalog designation, or Standard Nomenclature List (SNL) group "F".The United States Army Ordnance Corps Supply Catalog used an alpha-numeric nomenclature system from about the mid-1920s to about 1958.
The PLZ-05 is fitted with a digital fire control system, ballistic computers, a gunner day/night thermal imaging system, a laser range finder, and a commander-independent thermal viewer. In addition to indirect fire support, the main gun can be used as an anti-tank cannon or anti-fortification assault gun in an emergency.
Nanobubbles are nanoscopic and generally too small to be observed using the naked eye or a standard microscope, but can be observed using backscattering of light using tools such as green laser pointers. [12] Stable nanobubbles in bulk about 30-400 nanometers in diameter were first reported in the British scientific journal Nature in 1982. [12]
Eyepiece image of a naval rangefinder, showing the displaced image when not yet adjusted for range. The coincidence rangefinder uses a single eyepiece. Light from the target enters the rangefinder through two windows located at either end of the instrument. At either side the incident beam is reflected to the center of the optical bar by a ...
A center finder is a tool used to align the machining center to a precision location on a work piece. Often these locations might be marked using a layout method (coating the surface with layout stain and scribing a precise location with the intersection of the two lines identifying the position to be machined, etc.
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
The director was manned by a crew of 6: Director Officer, Assistant Control Officer, Pointer, Trainer, Range Finder Operator and Radar Operator. [36] The Director Officer also had a slew sight used to quickly point the director towards a new target. [37] Up to four Mark 37 Gun Fire Control Systems were installed on battleships.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
