Capture effect — In telecommunication, the capture effect, or FM capture effect, is a phenomenon associated with FM reception in which only the stronger of two signals at, or near, the same frequency will be demodulated. The capture effect is defined as the… … Wikipedia
capture — i. In flying aircraft, to control aircraft trajectory to intercept and then follow an external radio beam (as in ILS, or instrument landing system). ii. To detect and lock onto a target by a radar. iii. In flying, to reach a desired altitude or… … Aviation dictionary
Neutron Capture Therapy of Cancer — Neutron Capture Therapy (NCT) is a noninvasive therapeutic modality for treating locally invasive malignant tumors such as primary brain tumors and recurrent head and neck cancer. It is a two step procedure: first, the patient is injected with a… … 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

Boron Neutron Capture Therapy — (BNCT) is an experimental form of radiotherapy that utilizes a neutron beam that interacts with boron injected to a patient. BNCT depends on the interaction of slow neutrons with boron 10 to produce alpha particles and lithium nuclei, without… … Wikipedia
Tractor beam — A tractor beam is a hypothetical device with the ability to attract one object to another from a distance. Tractor beams are frequently used in science fiction. Less commonly, a similar beam that repels is called a pressor beam or repulsor beam … Wikipedia
Particle beam weapon — A particle beam weapon uses an ultra high energy beam of atoms or electrons (i.e., a particle beam) to damage a material target by hitting it, and thus disrupting its atomic and molecular structure. A particle beam weapon is a type of directed… … Wikipedia
