[0002] Encoder is the signal (such as bit stream) or data is arranged, converted into the signal form of signal, transmission and storage for use equipment. Encoder converts angular displacement or linear displacement into electrical signal, the former is called code disc, the latter is called code ruler. According to the reading mode, encoder can be divided into contact type and non-contact type two kinds;According to the working principle, encoder can be divided into incremental and absolute two types. Incremental encoder is converted into periodic electrical signal by displacement, and this electrical signal is changed into counting pulse, and the number of pulse is used to indicate the size of displacement. Absolute encoder corresponds to a certain digital code for each position, so its indication is only related to the starting and terminal position of measurement, and is independent of the intermediate process of measurement.
