The coarse grating linear encoder is a good type of phasemodulating linear displacement measuring system with optical scanning sersor. It has been widely used in machine tools. But its precision was limited by the sine form subdivision error. Having researched the error source of encoder system, the paper analyzed the experiment data of subdivision error and its related background noise by regulating the size of background noise in compensating circuit. Having analyzed with linear regression,the paper drew the linear relation between the subdivision error and background noise,which can be used as theoretical basis when amending errors. With error compensated, the system precision was improved near ten times, up to ±2μm. Meanwhile, the system precision has also been analyzed before and after the subdivision error was eliminated.
