Optical encoders are critical components in systems with rotating shafts or parts. Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals.

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 ...

As products and their components get smaller, the processes to produce them require manufacturers to find new ways to get the job done. For US Digital, which had to deal with tiny Mylar disks for its ...
