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 ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

The scientists increased the capacity by leaps and bounds using an optical disc with a 3D planar recording architecture, which uses a highly transparent, uniform photoresist film doped with ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

Forward-looking: As consumers increasingly turn toward digital distribution and data center operators try various storage methods, optical discs haven't stopped evolving. A recently published paper ...

Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a high-resolution absolute optical encoder for ...

In any application using motors for automation, there is a need to ensure accurate control of the motor. To make this possible, the position and speed of the rotor in the motor, which is usually ...

An unexpected revisit to my earlier post on mouse encoder hacking sparked a timely opportunity to reexamine quadrature encoders, this time with a clearer lens and a more targeted focus on their signal ...
