Abstract
A method and apparatus for binary coding of sensor signals received from a number of optoelectronic sensor elements employ an evaluator associated with each sensor element for generating binary output signals corresponding to the amount of charge generated by the associated sensor element. Selected pairs of evaluators are connected to an electronic switch, with one of the evaluator outputs serving to actuate the switch for the purpose of undertaking a charge quantity comparison between the associated sensors which are disposed a small distance from one another. Each evaluator includes a converter consisting of a switching transistor and a load element connected in series, and a barrier transistor connecting the output of the associated sensor element with the input of the converter, and a reset transistor for connecting the converter input with a constant voltage source.
