The interferometric baseline(vector between the inboard and outboard antennas) was measured using a combination of an optical target tracker, which measured the angles to several targets located on the outboard antenna structure; and an electronic ranging device used to measure the distance between inboard and outboard antennas.  2, record 1, English, - optical%20target%20tracker

The optics-equivalent in a radar imaging system is a long rectangular antenna which transmits and receives microwave energy. Resolution which is the ability of a system to differentiate between two closely spaced objects is dependent on focal length in optical sensors and in the along-track direction antenna length in radar systems.  1, record 2, English, - radar%20imaging%20system

L'élément «optique» d'un système radar imageur est une longue antenne rectangulaire, qui transmet et reçoit l'énergie des hyperfréquences. La résolution est la capacité d'un système de discriminer deux objets rapprochés. Elle dépend de la longueur focale des capteurs des systèmes optiques et, dans la direction azimutale, de la longueur de l'antenne des systèmes radar.  1, record 2, French, - syst%C3%A8me%20radar%20imageur

Electro-optic systems consist of a Mach-Zehnder optical modulator, laser light source, photo-detector, and attached antenna element. The laser light source and photodetector are connected to the optical modulator via fiber optic cables. The modulator is an interferometric system in which the optical power output varies with the voltage supplied from the antenna element.  3, record 3, English, - optical%20modulator

NASDA will conduct a series of experiments with optical inter-orbit communications, in cooperation with the European Space Agency(ESA), using ESA's geostationary satellite, the Advanced Relay and Technology Mission Satellite(ARTEMIS). A high-power laser device, a high-gain optical antenna, and a highly sensitive signal detector are required for this experiment since the distance between OICETS and ARTEMIS is estimated to be up to 45, 000 kilometers.  2, record 4, English, - advanced%20relay%20and%20technology%20mission%20satellite

Artemis est le dernier satellite de télécommunications mis au point par l'ESA et sa conception innovatrice fait appel à de nouvelles technologies jamais utilisées auparavant dans un satellite de télécommunications. En plus d'améliorer les communications mobiles et les retransmissions de données entre satellites, Artemis jouera un rôle important dans le développement de Galileo, le nouveau système européen de navigation satellitaire à l'échelle mondiale, en apportant une contribution précieuse pour faire progresser les télécommunications mobiles et les systèmes de navigation durant son séjour prévu de dix ans en orbite.  1, record 4, French, - satellite%20Artemis
