20120307165 | Imaging System - An imaging system for imaging an object onto an image sensor, and which has a front side facing the object and a rear side facing away from the object, the rear side being arranged behind the front side as viewed from the object. Furthermore, the imaging system has a light entrance device at the front side through which light coming from the object can enter into the imaging system. In this case, the light traverses the beam path between object and image sensor. At least one first and one second optical element are likewise present and are arranged at the rear side in such a way that they can influence the beam path. The light entrance device has an electrically switchable liquid crystal element which deflects the beam path at at least one first angle and a second angle which is different from the first angle depending on the electrical switching state. A discretely switchable focal length change is realized by this electrically effected change in the beam path. | 12-06-2012 |
20120327292 | Integrated imaging system - 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. | 12-27-2012 |
