Record number: 1, Textual support number: 1 CONT
Glories are formed by backward scattering from cloud or mist droplets. They appear on mountains and hillsides when the sun breaks through mist and when there is an opportunity to look downwards towards the antisolar point. They are always exactly opposite the sun and their delicate coloured rings are centered on the observer's shadow. 3, record 1, English, - glory

Une ou plusieurs séries d’anneaux colorés vus par un observateur autour de son ombre portée sur un nuage constitué principalement par de nombreuses petites gouttelettes d’eau, ou sur du brouillard ou, mais très rarement, sur de la rosée. 2, record 1, French, - gloire

La gloire est un phénomène rare et il faut être en altitude, notamment en avion, pour apercevoir le phénomène. Il s’agit en fait d’une série d’anneaux colorés qui se forment autour de l'ombre de l'avion projetée sur les nuages environnants. La disposition des couleurs est toujours la même : rouge à l'extérieur, violet à l'intérieur. Le phénomène est dû à la diffraction et la réflexion de la lumière solaire sur les gouttes d’eau des nuages. En certaines circonstances, les gloires peuvent se former autour de l'ombre de l'observateur, elle-même projetée sur les brouillards ou les nuages à proximité. 3, record 1, French, - gloire

L’ombroscopie est utilisée pour mesurer des pièces de décolletage et de tournage ou le profil d’outils de fraisage et de perçage. Les appareils les plus récents utilisent un laser comme source lumineuse. D’après le Cetim (Centre d’études des industries mécaniques), la précision obtenue est de 2 micromètres sur des diamètres de quelques dixièmes de millimètre à 50 millimètres. En ajoutant des axes de déplacement motorisé, en translation et en rotation, il est possible d’effectuer des mesures tridimensionnelles. 1, record 2, French, - ombroscopie

Temporal Paul wavelet analysis for instantaneous phase extraction using shadow moiré technique is proposed. Unlike the Morlet wavelet, the Paul wavelet has less restriction on the adjustment of wavelet parameters and can provide an optimal time and frequency resolution for a particular application by selecting the proper parameters. The Paul wavelet is a complex wavelet and is suitable for processing the temporal intensity data obtained from the shadow moiré technique for the phase retrieval. The proposed method can extract the phase information related to the state of the dynamic object at every instant in temporal domain. The phase information is associated to the displacement, three-dimensional (3D) surface-profile and the instantaneous state of the dynamic object. In addition, the instantaneous frequency of vibrating object can be obtained using the scale of the wavelet ridge by direct integration without temporal and spatial phase unwrapping. Thus the phase unwrapping error can be avoided. An experiment is conducted on the central loaded beam to demonstrate the validity of the proposed technique. 3, record 3, English, - shadow%20moir%C3%A9%20technique

The term “moiré” is ... a French word referring to “an irregular wavy finish usually produced on a fabric by pressing between engraved rollers” (Webster's 1981). In optics it refers to a beat pattern produced between two gratings of approximately equal spacing. It can be seen in everyday things such as the overlapping of two window screens, the rescreening of a half-tone picture, or with a striped shirt seen on television. The use of moiré for reduced sensitivity testing was introduced by Lord Rayleigh in 1874. Lord Rayleigh looked at the moiré between two identical gratings to determine their quality even though each individual grating could not be resolved under a microscope. ... Since Lord Rayleigh first noticed the phenomena of moiré fringes, moiré techniques have been used for a number of testing applications. Righi (1887) first noticed that the relative displacement of two gratings could be determined by observing the movement of the moiré fringes. The next significant advance in the use of moiré was presented by Weller and Shepherd (1948). They used moiré to measure the deformation of an object under applied stress by looking at the differences in a grating pattern before and after the applied stress. They were the first to use shadow moiré, where a grating is placed in front of a nonflat surface to determine the shape of the object behind it by using the shape of the moiré fringes. 4, record 3, English, - shadow%20moir%C3%A9%20technique

Le moiré d’ombre. Cette technique […] consiste à créer un moiré entre une grille de référence placée juste devant l'objet, et l'ombre de cette même grille projetée sur la surface étudiée. Les déformations de cette surface modifient le pas du réseau «ombre» créant ainsi le moiré. Une mesure du pas de ce moiré permet, à l'aide des équations précédentes, de remont3er aux déformations locales et de dresser la carte des hauteurs. 5, record 3, French, - technique%20du%20moir%C3%A9%20d%26rsquo%3Bombre
