Abstract
An imaging system having a front side and rear side enveloping a light transmitting space formed therebetween A front lens situated on the front side forms a portal through which light from an object enters into the light transmitting space wherein at least one optical element composed of glass or elastic material, liquid lenses or liquid crystal elements, and an image sensor are positioned to develop a folded beam path between the front lens and the image sensor, and a real image of the object on the image sensor. Electrically driving at least one optical element enables alteration of the focal length within the system in a manner switchable between at least two values. The change in focal length is realized with the aid of electrically controlled piezo-actuators or by an electric field applied to at least one variable optical element.
