This paper deals with the question of how to evaluate the performance of opto-electronic transducers for precision dimensional metrology, such as laser interferometers and linear scale systems, etc. For this purpose, the opto-electronic transducers are considered as a kind of communication system, and the concept of information capacity is used to summarize the basic technical data of the transducer. These data are usually listed in the operation manual of a transducer to show its warranted performance in various aspects.
