<p>An optoelectronic position measurement device having a code carrier that carries at least one optically registered position code and that is illuminated with optical radiation from a radiation source. At least one portion of the optical radiation is registered by at least one registration element, by means of which a signal dependent on the position code can be created and a position of the code carrier relative to the registration element can thus be registered, wherein the code carrier is movable relative to the registration element with a degree of freedom - in particular rotating or translating. The radiation source and code carrier are arranged and designed such that the optical radiation couples into the code carrier and is guided at least partially in a beam path in the interior of the code carrier lying in the extension level of the code carrier, in particular to the position code. The decoupling of the optical radiation occurs in a decoupling zone such that the registration element is illuminated by a substantially homogenous intensity distribution.</p> |
