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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

In robotics, movements must be precise and well-controlled. As robots are asked to do more as industry becomes more familiar with the technology, there will be an increasing need for high accuracy ...
