Abstract
In an imaging device for imaging a target, a photodetector with a two-dimensional light sensitive pixel area is provided. The two-dimensional light sensitive pixel area is divided into a plurality of split pixel areas. An imaging optics defines a plurality of segments of an FOV (field of view). The plurality of segments of the FOV respectively correspond to the plurality of split pixel areas of the photodetector. The imaging optics aligns, in a predetermined direction, the plurality of segments of the FOV to form a predetermined-direction oriented FOV so that the target is at least partially contained in the predetermined-direction oriented FOV.
Claims22
An imaging device for imaging a target, the imaging device comprising:
- a photodetector with a two-dimensional light sensitive pixel area, the two-dimensional light sensitive pixel area being divided into a plurality of split pixel areas, each of the split pixel areas being composed of a plurality of pixels;
- and
- an imaging optics configured to:
- define a plurality of segments of an FOV (field of view), the plurality of segments of the FOV respectively corresponding to the plurality of split pixel areas of the photodetector;
- and
- align, in a predetermined direction, the plurality of segments of the FOV to form a predetermined-direction oriented FOV so that the target is at least partially contained in the predetermined-direction oriented FOV,
