摘要： A photodiode detector array for optical encoders includes a plurality of photodiodes, each of the photodiodes providing a scanning signal with a defined phase relationship to a scale when the detector array moves relative to the scale. A plurality of switching elements is provided for selectively combining each of the photodiodes with other photo diodes in a defined manner. The switching elements allow the photodiodes to be unambiguously combined for at least two different scale radii so that a defined number of phase shifted scanning signals is generated in each case. The combination of the photodiodes differs between the at least two different scale radii.

摘要： A position-measuring device having integrated function testing includes a position-recording unit, a processing unit, and a control-word generator. In a positional-data request, a positional-data word is first generated in the position-recording unit and output to the processing unit. There, the position data word is processed into a position value. Subsequently, a control-data word is generated in the position-recording unit according to the specification of the control-word generator and output to the processing unit. The processing unit processes the control-data word into a control value which has a defined mathematical relationship to the position value.
