3Beam-powered propulsion — is a class of spacecraft propulsion mechanisms that use energy beamed to the spacecraft from a remote power plant. Most designs are rocket engines where the energy is provided by the beam, and is used to superheat propellant that then provides… …
4Beam's eye view — (or BEV) is an imaging technique used in radiation therapy for the quality assurance and planning of External Beam Radiation Therapy treatments. These are primarily used to ensure that the relative orientation of the patient and the treatment… …
5Beam tracing — is a derivative of the ray tracing algorithm that replaces rays, which have no thickness, with beams. Beams are shaped like unbounded pyramids, with (possibly complex) polygonal cross sections. Beam tracing was first proposed by Paul Heckbert and …
6Beam steering — (also spelled beamsteering or beam steering) is about changing the direction of the main lobe of a radiation pattern. In radio systems, beam steering may be accomplished by switching antenna elements or by changing the relative phases of the RF… …
7Source Four PAR — The Electronic Theatre Controls Source Four PAR fixture is considered an improvement upon traditional Parabolic aluminized reflector light cans. The Source Four PAR uses an HPL lamp (the same used in other ETC Source Four fixtures), a distinct… …
8Source Four — The ETC (Electronic Theatre Controls) Source Four (also known unofficially as Source 4 or S4 ) is an ellipsoidal reflector spotlight, a type of spotlight used in stage lighting. The ETC Source Four revolutionized stage lighting in 1992 cite news… …
9Source function — The source function is a characteristic of a stellar atmosphere, and in the case of no scattering of photons, describes the ratio of the emission coefficient to the absorption coefficient. It is a measure of how photons in a light beam are… …
