Technological improvements in position sensing

To describe new technological approaches and improvements to existing methods of measuring position in automation, sports and general applications.

Starts with interesting applications of established sensor technology in motorsports and aircraft manufacture. Then examines some new position sensors based on novel technology.

Optical techniques including lasers and linear encoding enable high precision position sensing over long distances. Laser scanning systems have some advantages over vision systems for pick and place applications. Differential global positioning system (GPS) and carrier‐wave techniques are giving millimeter accuracy to GPSs.

Highlights the more exciting aspects of position sensing.
