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 ...

Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code , is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
The Parsons code, formally named the Parsons code for melodic contours, is a simple notation used to identify a piece of music through melodic motion – movements of the pitch up and down. [1] [2] Denys Parsons (father of Alan Parsons [3] ) developed this system for his 1975 book The Directory of Tunes and Musical Themes .

A coincidence rangefinder or coincidence telemeter is a type of rangefinder that uses the principle of triangulation and an optical device to allow an operator to determine the distance to a visible object. There are subtypes split-image telemeter, inverted image, or double-image telemeter with different principles how two images in a single ...
Accelerator physics codes. A charged particle accelerator is a complex machine that takes elementary charged particles and accelerates them to very high energies. Accelerator physics is a field of physics encompassing all the aspects required to design and operate the equipment and to understand the resulting dynamics of the charged particles.
High-frequency direction finding. High-frequency direction finding, usually known by its abbreviation HF/DF or nickname huff-duff, is a type of radio direction finder (RDF) introduced in World War II. High frequency (HF) refers to a radio band that can effectively communicate over long distances; for example, between U-boats and their land ...
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images .
