A confocal imaging system using optical fibres is provided which has a flexible near confocal optical transmission means having a light collection end (71) adjacent to a light collection end (70) of the confocal optical transmission means and adapted to transmit only near confocal light (S', T') emerging from points in the object (S, T) located within a range of distances above and below the focal plane, in such a manner that a selected portion of the near confocal light emerging from greater than any selected distance within said range is substantially separable from the remainder. The system also has variable selection means (73, 76) to exclude from detection said selected portion.
L'invention concerne un système d'imagerie confocale dans lequel on utilise des fibres optiques et qui présente des moyens flexibles de transmission optique quasi confocale pourvus d'une extrémité (71) captant la lumière, adjacente à une extrémité (70) captant la lumière des moyens de transmission optique confocale et conçue pour ne transmettre que la lumière (S', T') quasi confocale émergeant de points d'un objet (S, T) placé dans une plage de distances se situant au-dessus et en dessous du plan focal, de telle façon qu'une portion choisie de la lumière quasi confocale, émergeant d'une distance supérieure à une quelconque distance choisie dans ladite plage, peut être sensiblement séparée du reste. Ce système présente également des moyens (73, 76) de sélection variables permettant d'exclure de la détection ladite portion choisie.
