Rotary encoder - Wikipedia

A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. There are two main types of rotary encoder: absolute and incremental.

Optical Rotary Encoders | How Absolute & Incremental ...

A rotary encoder using optical sensing technology relies on the rotation of an internal code disc that has opaque lines and patterns on it. The disc is rotated (hence the name rotary encoder) in a beam of light such as an LED and the markings on the disc act as shutters blocking and unblocking the light.

Optical Rotary Encoders | Dynapar

An optical rotary encoder has a moving disk, with concentric tracks etched into the disk. Periodically, these tracks have an opening, called a window. The windows of every track are offset, so that each revolution of the optical rotary encoder has a different light/dark pattern.
