A rotary encoder is a type of position sensor which is used for defining the angular position of a rotating shaft. It generates an electrical signal, either equivalent or digital, according to the rotational movement. There are numerous types of rotary encoders like: absolute rotary encoder, incremental rotary encoder Light Duty Incremental Encoders and many other. These encoders are categorized by either Output Signal or Sensing Technology.

How does shaft encoder work?
A shaft encoder is also known as a rotary encoder. The shaft encoder converts an angular position of a shaft to a digital code.

How does light behave to make rotary encoder work?
A rotary encoder consists of three main parts: light source, optical encoder disc and light sensors. The light source provides the light source to several light sensors. There is an optical encoder disc that selectively blocks light from light source to light sensor. If the light sensor is receiving light, it is first state of electronic circuit. If the light from light source to the sensor is blocked by optical encoder, then sensor is not receiving light and this is second state of sensor output. Therefore, each sensor has two ouputs possible, high or low. Output from one sensor is called a "bit" so for 4 sensors, it is 4 bit output. The light encoder disc is a plastic disc with some area opaque and other areas transparent. Depending upon its rotating position, it passes light to some sensors and blocks light to other remaining sensors. The combination of states of multiple light sensors at a given time due to a certain rotary position of rotary encoder disc is the multi-bit output of that rotary encoder. This multi-bit logic output is used to sense the position, direction of rotation and rotating speed of the rotary encoder. You can read more about rotary encoders at the links given.

What is an absolute encoder?
An absolute optical encoder is a type of rotary encoder. The optical disk is designed to produce a digital word which distinguishes N distinct positions of the shaft. Common types of numerical encoding used in the absolute encoder include gray and binary codes. http://www.motioncontrolguide.com/learn/guides/encoders-guide/
