Beam 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… … Wikipedia
Diffractive beam splitter — 7x7 matrix using green laser and diff. beam splitter (Courtesy of Holo Or) The diffractive beam splitter [1] [2] (also known as multispot beam generator … Wikipedia
Phased array — This article is about general theory and electromagnetic phased array. For the ultrasonic and medical imaging application, see phased array ultrasonics. In wave theory, a phased array is a group of antennas in which the relative phases of the… … Wikipedia
Thinned array curse — The thinned array curse (sometimes, sparse array curse ) is a theorem in electromagnetic theory of transmitters. It states that a transmitting aperture which is synthesized by a coherent phased array of smaller apertures that are spaced apart… … Wikipedia
Line array — The term line array means a speaker system that is made up of a varying number of vertically arranged units which give the effect of a single sound source with the same dimensions as the total of the unit of which is made up, the performance of… … Wikipedia
Lorenz beam — The Lorenz beam blind landing system was an air radio navigation system in use from the late 1930s. The name refers to the company that produced the system; Lorenz referred to it simply as the Ultrakurzwellen Landefunkfeuer, German for ultra… … Wikipedia
Electronically scanned array — An electronically scanned array (ESA), or a phased array, offers many advantages over mechanically scanned antennas such as instantaneous beam scanning, the availability of multiple concurrent agile beams and concurrently operating radar modes.… … Wikipedia
Phased array ultrasonics — Phased Array (PA) ultrasonics is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing, originally pioneered by Albert Macovski of Stanford University. [cite web |url=… … Wikipedia
Halbach array — A Halbach array, showing the orientation of each piece s magnetic field. This array would give a strong field underneath, while the field above would cancel. The flux diagram of a Halbach array A Halbach array is a special arra … 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
phased-array antenna — An antenna that consists of a number of elements and in which the direction of the beam can be changed by varying the relative phase of the signal applied to each of these elements. The phased array antenna scans electronically. Phased array may… … Aviation dictionary
