Read-out unit for an optical position measuring device
摘要
<p>The unit produces a periodic incremental signal and a reference pulse signal at a defined reference position. A filter effect is achieved by designing the reference mark sensing field or one or more reference mark detector elements so that the periodic incremental signal component of the reference pulse signal is substantially eliminated adjacent to the reference position.</p>
