1Laser 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… …
2radar — /ray dahr/, n. 1. Electronics. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. 2. a means or sense of awareness or… …
3Radar gun — A radar gun or speed gun is a small Doppler radar used to detect the speed of objects. A radar gun does not return information regarding the object s position or any information concerning the car e.g. Registration etc. It relies on the Doppler… …

5Radar detector — A radar detector, sometimes called a fuzz buster, is a passive electronic device used by motorists to determine if their speed is being monitored by law enforcement agencies via a radar unit, and thereby, potentially avoiding prosecution for… …
6History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… …
7Continuous-wave radar — is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects.[1]Continuous wave (CW) radar uses Doppler, which renders the radar immune to interference from… …
8Quantum cascade laser — Quantum cascade lasers (QCLs) are semiconductor lasers that emit in the mid to far infrared portion of the electromagnetic spectrum and were first demonstrated by Jerome Faist, Federico Capasso, Deborah Sivco, Carlo Sirtori, Albert Hutchinson,… …
