Document Type and Number:
WIPO Patent Application WO/2012/073178
Kind Code:
A3
Abstract:
The invention relates to a double telecentric optical system (100) and its use in a sensor device(1000), wherein said optical system (100) comprises a single focusing element, for example a lens (101). A mirror element (102) is arranged at the focal point (F) of this focusing element (101) to reflect incoming light rays back to the focusing element (101). Incoming and reflected light rays preferably pass through different parts (101a, 101b) of the focusing element (101), allowing a spatially separated arrangement of an object (3) and its image (I).
