The invention relates to the technical field of precision measuring instruments, in particular to an encoder reading head which is characterized by comprising a reading module used for reading optical signals emitted by a code channel, a signal transmission module used for transmitting the optical signals and an optical energy enhancing module used for enhancing the optical signals. And the photoelectric conversion module is used for converting an optical signal into an electric signal. Through a reading-conduction-enhancement-conversion reading method, the method has the advantages of being accurate in reading and reducing reading errors. 本发明涉及精密测量器械的技术领域，更具体地说，它涉及一种编码器读数头，其技术方案要点是：包括用于读取码道发射的光信号的读取模块，用于传输光信号的信号传导模块，用于增强光信号的光能增强模块，以及将光信号转化为电信号的光电转化模块。本发明通过"读取-传导-增强-转化"的读取方法，具有读取精准、减少读取误差的优点。
