摘要
Process for high-precision measurement of the phase relationship and phase displacement, respectively, of two pulse trains wherein rotational angles of two rotating bodies are quantized and converted by incremental shaft encoders into pulse trains, and the pulse trains are applicable for calculating the respective phase relationship and phase displacement, which comprises the steps of: a. counting the pulse trains in at least two different counters; b. forming a digital difference of the two counts; c. converting the digital difference into an analog signal; d. decoding the analog signal; and e. displaying the decoded analog signal; and a device for performing the process.
