• Beam (nautical) — The beam of a ship is its width at the widest point, or at the mid point of its length. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at expense of reserve stability in the event of a capsize,… …   Wikipedia

• Beam (structure) — A statically determinate beam, bending (sagging) under an evenly distributed load. A beam is a horizontal structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the… …   Wikipedia

• Beam parameter product — In laser science, the beam parameter product (BPP) is the product of a laser beam s divergence angle (half angle) and the radius of the beam at its narrowest point (the beam waist).cite web|url=http://www.rp photonics.com/beam parameter… …   Wikipedia

• Laser beam profiler — A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers ultraviolet, visible, infrared, continuous… …   Wikipedia

• Blip-to-scan ratio — In radar systems, the blip to scan ratio, or blip/scan, is the ratio of the number of times a target appears on a radar display to the number of times it could have been seen. [ [http://www.answers.com/topic/blip scan ratio?cat=technology blip… …   Wikipedia

• Focal length — The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. Thin lens approximation For… …   Wikipedia
