Title:
OPTICAL ELEMENT FOR MULTIFOCAL IMAGING IN A CAMERA FOR VEHICLE APPLICATIONS
Document Type and Number:
WIPO Patent Application WO/2011/153978
Kind Code:
A3
Abstract:
The invention relates to an optical element (POE) for multifocal imaging in a camera for vehicle applications comprising - at least one first and at least one second partial region (T1, T2), arranged alongside one another, wherein - the at least one first partial region (T1) is designed to bring about a first axial offset of the beam path in the camera, - the at least one second partial region (T2) is designed to bring about a second axial offset of the beam path in the camera, - the first axial offset differs from the second axial offset, - the first axial offset is provided for long-range imaging in the camera, - the second axial offset is provided for short-range imaging in the camera, and wherein - the second partial region (T2) differs from the first partial region (T1) in that its cross section (T2_d1, T2_d2) changes in a vertical direction (20) of the short-range imaging.
