Optical sensors are successfully used for measurement in many areas, such as the position sensing of moving objects or the measurement of distance. The types of sensor elements used in these ...

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

A common approach to measuring distance or angle in a rotating system is by using an incremental encoder or resolver. The majority of industrial applications, such as machines or drives, are dominated ...

The Korea Research Institute of Standards and Science has successfully developed a length measurement system that achieves a level of precision approaching the theoretical limit allowed by quantum ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...
