coherent detection
1Coherent anti-Stokes Raman spectroscopy — Coherent anti Stokes Raman spectroscopy, also called Coherent anti Stokes Raman scattering spectroscopy (CARS), is a form of spectroscopy used primarily in chemistry, physics and related fields. It is sensitive to the same vibrational signatures… …
2Coherent states — In quantum mechanics a coherent state is a specific kind of quantum state of the quantum harmonic oscillator whose dynamics most closely resembles the oscillating behaviour of a classical harmonic oscillator. It was the first example of quantum… …
3Coherent state — In quantum mechanics a coherent state is a specific kind of quantum state of the quantum harmonic oscillator whose dynamics most closely resemble the oscillating behaviour of a classical harmonic oscillator system. It was the first example of… …
4Détection de personne — Un exemple de détection de personnes sur une voie de circulation La détection de personne est un domaine de la vision par ordinateur consistant à détecter un humain dans une image numérique. C est un cas particulier de détection d objet, où l on… …
5Coherent anti-Stokes Raman spectroscopy — Dieser Artikel oder Abschnitt bedarf einer Überarbeitung. Näheres ist auf der Diskussionsseite angegeben. Hilf mit, ihn zu verbessern, und entferne anschließend diese Markierung. Die nicht lineare Raman Spektroskopie versteht man die nichtlineare …
6Optical heterodyne detection — is an important special case of heterodyne detection. In heterodyne detection, a signal of interest at some frequency is non linearly mixed with a reference local oscillator (LO) that is set at a close by frequency. The desired outcome is the… …
7Neutron detection — is the effective detection of neutrons entering a well positioned detector. There are two key aspects to effective neutron detection: hardware and software. Detection hardware refers to the kind of neutron detector used (the most common today is… …
8Méthodes de détection des exoplanètes — En astronomie, la recherche des exoplanètes fait appel à plusieurs méthodes de détection des exoplanètes. La majorité de ces méthodes sont à l heure actuelle indirectes, puisque la proximité de ces planètes avec leur étoile est si grande que leur …
9Target Acquisition Minefield Detection System — (ASTAMIDS) is the latest weapon in the fight against improvised explosive devices (IED). It will provide a Unit of Action (UA) asset that can be used in Tactical Operations in day or night to detect and locate surface obstacles and recently… …
10Optical hybrid — A 90° optical hybrid is a six port device that is used for coherent signal demodulation for either homodyne or heterodyne detection. It would mix the incoming signal with the four quadratural states associated with the reference signal in the… …
