Optical encoders are the unsung heroes of precision motion—converting rotation or linear travel into clean, reliable digital signals. From robotic joints and CNC spindles to semiconductor stages and medical devices, they deliver micrometer-level accuracy, high resolution, and excellent repeatability. This deep dive explains how they work, the difference between incremental and absolut... https://twizzr.worldsofrp.com/read-blog/767_illuminating-precision-a-deep-dive-into-optical-encoders.html
