The localizer transmission, at very high frequency [VHF] frequencies(108-122 Mhz), provides information to the aircraft as to whether it is flying to the left or right of the centre line of the runway it is approaching. The localizer receiver output is proportional to the angular deviation... of the aircraft from the localizer beam centre line which in turn corresponds with the centre line of the runway. 4, record 1, English, - ILS%20localizer%20track

The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices. A Faraday cell is a piece of crystal, which changes the phase of a light wave traveling through it as a function of an applied magnetic field. The effect is nonreciprocal. A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length. This scheme eliminates the vibration problem, but retains the random walk angular position error. 2, record 18, English, - random%20walk

[...] si le rayon de Larmor de la particule est tel qu'il existe des valeurs de l'angle pour lesquelles la relation (3.16) est vérifiée, la particule subira alors une déflection qui fera varier son angle d'attaque, entraînant du même coup une déviation de sa trajectoire originelle. Le processus alors engagé amènera la particule à rencontrer d'autres résonances qui entraîneront alors une marche au hasard pour la particule. Cette marche au hasard est la base du processus diffusif qui veut qu'une particule perde rapidement le souvenir de sa trajectoire initiale. L'exemple présenté ici est évidemment simpliste (la relation 3.16 n'est pas [toujours valide]). Néanmoins, dans le cas des champs magnétiques chaotiques à trois dimensions, l'idée de résonance reste. Ainsi, il faudra que la particule suive une relation similaire à (3.16) pour qu'elle rencontre des résonances avec le chaos.

Le but de notre expérience est de mesurer une accélération angulaire. Pour ce faire, un interféromètre à effet Sagnac sera utilisé. Il s'agit d'un dispositif expérimental permettant l'analyse d'une figure d'interférence produite par un faisceau laser. Le faisceau est coupé en deux par un miroir semi-transparent et, à la différence de l'interféromètre de Michelson, le trajet suivi par les rayons est circulaire. Chaque rayon tourne dans un sens différent et donc, selon l'état de rotation du système, le déphasage entre les rayons est sensible à l'accélération angulaire du dispositif. Quand l'interféromètre de Michelson permet de mesurer une accélération linéaire, l'interféromètre à effet Sagnac permet de mesurer une accélération angulaire. Le principe de cet effet correspond à un effet Doppler rotationnel. Il a été découvert par Sagnac en 1913.

The Sagnac effect... is understood as a phase shift of one counterpropagating wave with respect to another wave of this mode in a rotating ring interferometer, the shift being directly proportional to the angular velocity of rotation, the area enclosed by the interferometer, and the wave frequency. The Sagnac effect applies to a kinematic effect of the special theory of relativity(STR) and... ensues from the relativistic law of velocity composition. 2, record 24, English, - Sagnac%20effect%20rotating%20ring%20interferometer

Le but de notre expérience est de mesurer une accélération angulaire. Pour ce faire, un interféromètre à effet Sagnac sera utilisé. Il s'agit d'un dispositif expérimental permettant l'analyse d'une figure d'interférence produite par un faisceau laser. Le faisceau est coupé en deux par un miroir semi-transparent et, à la différence de l'interféromètre de Michelson, le trajet suivi par les rayons est circulaire. Chaque rayon tourne dans un sens différent et donc, selon l'état de rotation du système, le déphasage entre les rayons est sensible à l'accélération angulaire du dispositif. Quand l'interféromètre de Michelson permet de mesurer une accélération linéaire, l'interféromètre à effet Sagnac permet de mesurer une accélération angulaire. Le principe de cet effet correspond à un effet Doppler rotationnel. Il a été découvert par Sagnac en 1913. Cet interféromètre annulaire se résume en deux formules. 3, record 24, French, - interf%C3%A9rom%C3%A8tre%20de%20Sagnac%20circulaire

The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices. A Faraday cell is a piece of crystal, which changes the phase of a light wave traveling through it as a function of an applied magnetic field. The effect is nonreciprocal. A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length. This scheme eliminates the vibration problem, but retains the random walk angular position error. 1, record 25, English, - random%20walk%20angular%20position%20error

Gyrolaser [...] Le blocage de fréquence immobilise l'onde stationnaire; il résulte d'une interaction (transfert d'énergie thermique) entre les 2 ondes lumineuses : c'est la conséquence de minimes imperfections des miroirs du gyroscope qui diffusent une faible partie de la lumière incidente en sens opposé à la trajectoire initiale. («cheminement aléatoire» = random walk) On ajoute un vibreur qui garde la cavité en mouvement; la vibration des miroirs permet d'éliminer ce seuil. 2, record 25, French, - erreur%20de%20position%20angulaire%20due%20au%20cheminement%20al%C3%A9atoire
