The Verification of Accuracy and Resolution for High -resolution Photoelectric Rotary and Angle Encoders
Geng Lihong et al
thug micromotion screw, angular surface and sine bar, a standard micro-angle is produced by the mothed of four times contraction principle. The resolution and the interpolation error of high-resolution rotary and angle encoders are measured by this standardmicro-angle. Measuring accuracy of the encoders and data proccessing are also mentioned in this paper.
