description | A variable focus illuminator includes an array of light sources and a movable lens plate positioned immediately in front of the array of light sources. The lens plate includes a plurality of lenses that redirect the light produced by the light sources, such that different positions of the lens plate result in different sizes of the field illuminated by the variable focus illuminator. The lens plate may be movable in translation, rotation, or both. The variable focus illuminator may also include a cover plate in front of the movable lens plate, which may also include a plurality of cover plate lenses. The variable focus illuminator may be varifocal, or may include a zoom capability. The variable focus illuminator may be part of a system that includes a camera, and the system may also include a pan/tilt mechanism.
La présente invention a trait à un illuminateur à focale variable qui inclut un réseau de sources lumineuses et une plaque de lentille mobile qui est placée immédiatement devant le réseau de sources lumineuses. La plaque de lentille inclut une pluralité de lentilles qui redirigent la lumière produite par les sources lumineuses, de sorte que différentes positions de la plaque de lentille engendrent différentes tailles du champ éclairé par l'illuminateur à focale variable. La plaque de lentille peut être mobile par translation, rotation ou les deux. L'illuminateur à focale variable peut aussi inclure une plaque de couvercle devant la plaque de lentille mobile, qui peut aussi inclure une pluralité de lentilles de plaque de couvercle. L'illuminateur à focale variable peut être un verre à foyer progressif, ou peut inclure une capacité de zoom. L'illuminateur à focale variable peut faire partie d'un système qui inclut une caméra et le système peut également inclure un mécanisme de panoramique horizontal-vertical. |
