Encoders: the pulse of motion

The tried-and-true method of measuring distance and speed of rotary and linear motion requires an understanding of encoders

Encoders are used to measure distance. Rotary encoders measure the angular distance around the circumference of a circle, often in degrees. Linear encoders measure the distance an object moves in a straight line. Measuring the number of pulses over a set period produces the property of speed. Encoders are further classified as incremental or absolute.
