The monitoring of rotation can involve such sensor types as proximity, photoelectric, resolvers, encoders, and tachometer generators. Most determine direction of rotation, speed, and angular position ...

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 ...

Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...
