A New Image Grating Sensor for Linear Displacement Measurement and Its Error Analysis

To improve the accuracy of the current vision-based linear displacement measurement in a large range, a new type of linear displacement sensing system, namely, image grating, is proposed in this paper. The proposed system included a patterned glass plate attached to the moving object and an ultra-lo...
