This image shows several encoder disks: lower resolutions are on the left and higher resolutions are on the right. Encoders are a key component of motion control systems in that they send a feedback ...
Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...
This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...
