Abstract

L'invention concerne la détermination des paramètres d'une direction. Elle se rapporte à un dispositif dans lequel un objectif forme une image dun objet sur un cache rotatif ayant une partie transparente 21 et une partie opaque 22. Ces deux parties sont limitees par un segment de droite 25 et par un segment 26 de spirale logarithmique, si bien que la sensibilité peut être élevée lorsque le champ est faible et le champ peut être important, pour une sensibilité modérée. Application au guidage des objets autopropulsés.The invention relates to determining the parameters of a direction. It relates to a device in which an objective forms an image of an object on a rotating cover having a transparent part 21 and an opaque part 22. These two parts are bounded by a line segment 25 and by a segment 26 of a logarithmic spiral, so that the sensitivity can be high when the field is small and the field can be large, for moderate sensitivity. Application to the guidance of self-propelled objects.
