Abstract:
1. An imaging system for imaging an object onto an image sensor and wherein light traverses a beam path between the object and the image sensor, the imaging system comprising: a) a front side facing the object; b) a rear side which faces away from the object and which is arranged behind the front side, as viewed from the object; c) a front lens or lens combination on the front side through which light coming from the object enters into the imaging system; d) at least one optical element which is arranged on the rear side or front side and can influence the beam path within the imaging system in such a way characterized e) in that the at least one optical element has a liquid lens; f) in that a reflective material is arranged at the underside of the liquid lens; g) in that at least one optical property of the liquid lens can be altered by an electrical voltage being applied to the liquid lens; h) in that the liquid lens is embodied in such a way that the focal length of the imaging system can be altered by means of an electrical driving of the liquid lens; i) as a result of which at least one first value of the focal length and a second value, different than the first value, of the focal length can be set for the imaging system depending on the electrical switching state of the liquid lens.
