The interest of a ground based Slit Aperture Telescope(SAT) which operates with a long thin pupil has been underlined for applications in the field of high angular resolution observations by speckle-interferometric techniques. The SAT lies halfway between the Michelson stellar interferometer and the standard telescope with circular aperture. The authors present the principle of an image processing algorithm which could be used associated with a space-SAT for astronomical image reconstruction. A full coverage of the two dimensional Fourier plane of the astronomical object can be obtained by rotating the SAT around its optical axis. The method of image reconstruction is analogous to those used in computerized tomography and uses Fast Fourier Transform algorithm. The interest of the use of a rotating space-SAT among synthetic apertures is its capability of giving a reconstructed image of the astronomical object simultaneously in several light wavelengths, each colored image being comparable with the others for fruitful astrophysical applications. 3, record 27, English, - slit%20aperture%20telescope

Le principe de fonctionnement des GFO [gyroscopes à fibres optiques] correspond non plus à une cavité optique résonante mais à une bobine de fibre optique qui peut atteindre plusieurs kilomètres. La différence de chemin optique rencontrée par les deux ondes contra-propagatives, en présence d'une rotation suivant l'axe de la bobine, est mise en évidence par une différence de phase au point de combinaison. Il ne s'agit donc plus d'une différence de fréquence des deux ondes comme dans le cas du gyrolaser, mais d'une différence de phase. 3, record 46, French, - bobine%20de%20fibre%20optique

A more advanced type of gyro is the optical gyroscope. These devices are based on two counter-rotating beams of light travelling in a ring-like structure. The interaction of the two light beams produces a standing wave pattern. If the ring is then rotated about its centre axis(think of a torus spinning around its core), one of the beams has to travel a slightly longer distance, and the other a slightly shorter distance to get back to where they started. This will cause a shift in the pattern of the standing wave, and this can be measured to determine the rate of rotation. 3, record 47, English, - optical%20gyro

Most people would remember the classic rotating disc gyroscope, which belongs to the mechanical group. One of today’s high precision gyros is still the mechanical, rotating gyro; however it is dependent on linear accelerations because of its mechanical measuring principle. The optical group comprises the fibre optic- and laser types. These use the Sagnac Effect (named after its French discoverer), which, when the sensor is turned, results in a difference in transit time between two light waves passing through the same optical path but in opposite directions. Optical gyros therefore do not depend on acceleration as gyros in the mechanical group. This is one of their biggest advantages ... 4, record 47, English, - optical%20gyro

Réaliser un gyroscope optique d'un prix de revient de quelques centaines de francs. Voilà une prouesse technologique quand on sait que les systèmes actuels, les gyroscopes laser, coûtent entre 100 000 francs et 1 million de francs. La solution mise au point par Mohamed Bouamra, chercheur à l'École nationale supérieure de physique de Strasbourg, tient à une habile substitution de technologies : une simple diode électroluminescente remplace le laser, tandis que des banales fibres optiques multimodes prennent la place des coûteuses fibres monomodes. 2, record 47, French, - gyroscope%20optique
