Read-out tractor vehicle display

摘要

The read-out tractor vehicle display consists of a foil (1) having embedded optical fibres (2). A perforated template (3) is positioned in front of this foil (1). A light beam (4) is guided from an immovably disposed read-out device via the optical fibres (2) and the template (3) onto a detector (5). As a result, bright/dark information is received in the detector (5) in the form of a digital message depending on the arrangement of the perforations in the template (3). <IMAGE>
