Compensation for dynamic subdivision error when the grating displacement sensor code disc is stained

When the code disc of a displacement sensor gains dust or other impurities, its moiré fringe signal will deviate from the standard range, which increases subdivision error. In this study, a high-speed AD converter was used to collect the moiré fringe signal of a sensor in real time and to extract th...
