Linear encoders are the sensors that detect linear movements as absolute position values without establishing a physical contact with the object. Linear encoders play a crucial role in determining the ...

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, ...

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 ...
