Abstract
An imaging system for a vehicle includes an image sensor for detecting electromagnetic radiation, a first lens unit and a second lens unit for focusing electromagnetic radiation, and at least one transflective unit, with the transflective unit being configured to project electromagnetic radiation from the first lens unit or from the second lens unit essentially perpendicularly on the image sensor, where the first lens unit has a first optical axis and the second lens unit has a second optical axis crossing the first optical axis at a crossing point, and the transflective unit is arranged between the image sensor, the first lens unit, and the second lens unit, preferably at the crossing point. A rear view display device includes at least one imaging system, and a vehicle includes at least one imaging system.
Claims14
An imaging system for a vehicle, comprising:
- an image sensor for detecting electromagnetic radiation;
- a first lens unit and a second lens unit for focusing electromagnetic radiation;
- and
- at least one transflective unit, with the at least one transflective unit being configured to project electromagnetic radiation from at least one of the first lens unit and the second lens unit essentially perpendicularly on the image sensor, the at least one transflective unit comprising at least one transflector that can operate in at least one of a reflective mode and a transmissive mode depending on a corresponding input signal that is applied to the at least one transflective unit, wherein
- the first lens unit has a first optical axis and the second lens unit has a second optical axis crossing the first optical axis at a crossing point, and
- the at least one transflective unit, which is arranged between the image sensor, the first lens unit, and the second lens unit at the crossing point, comprises
- at least one first shutter-glass having a reflective mode and a transmissive mode, with the optical axis of the at least one first shutter-glass crossing the first and the second optical axes in the crossing point within the at least one first shutter-glass;
- and
- at least one second shutter-glass, the at least one second shutter-glass being arranged between the first lens unit and the at least one first shutter-glass to control transmission of electromagnetic radiation from the first lens unit to the at least one first shutter-glass, and the at least one second shutter-glass is at least partially at the crossing point of the first optical axis of the first lens unit and the second optical axis of the second lens unit.
