High-Precision Digital Rotary Encoder Based on Dot-Matrix Gratings

In this paper, a high-precision digital rotary encoder based on dot-matrix gratings (DMGs) is proposed for detecting shaft rotation. The DMG-based encoder is composed of a laser diode, a beam-shaping lens, a code disc, and a detector. In principle, a shaped rectangular beam illuminates a stripe of D...
