Abstract

An optoelectronic sensor includes optoelectronic converter elements having photosensitive surfaces arranged in a one or two dimensional array. A transparent cover protects the photosensitive surfaces of the optoelectronic converter elements. At least one portion of the transparent cover is shaped to include a light deflecting element such as a prism which enables the optoelectronic converter elements to be exposed to light beams coming from different directions.
