Abstract
An encoder operates in accordance with the transparent scanning principle. The encoder includes a rotating shaft, a partial disk connected nonrotatably concentrically with the shaft, an illuminating unit, and a scanning receiver located axially in front of the end of the shaft. The illuminating unit is connected nonrotatably centrally with the shaft and rotates with the shaft on the side of a partial disk that faces away from the scanning receiver. The scanning receiver includes a monolithic photoreceiver array which is formed with photosensitive sensor areas associated with an angular displacement of the partial disk.
