Optical encoder disks and strips are components of rotary and linear encoders, respectively. They are usually made of metal, plastic, glass, or paper. Optical encoders are sensors that translate ...

Microlens array based light-field imaging generally suffers from an intrinsic trade-off between the spatial and angular resolutions. To this end, scientists in China and German jointly proposed a ...

Because they have higher resolution and accuracy, these encoders are often used in applications that need high precision, ...

The use of 100% hard-tooled parts and patented light-pipe technology for optical switching enables the Series 62AG optical encoder from Grayhill Inc. to be price-competitive with mechanical encoders ...

The sensing mechanism in an incremental optical rotary encoder consists primarily of a light source, code wheel, and optical detector. As the code wheel turns, a ring of alternating opaque and ...

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 ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

There is an ever-increasing demand for accuracy in many manufacturing industries. Adding to this general need for higher accuracy is the fact that industry sectors such as semiconductors and ...

A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...
