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/


What are the applications of gray code?

Gray code is useful because only one bit changes at a time. When used as encoders for a position sensor, for instance, if the sensor were right at the edge of a change boundary, there is uncertainty as to position. Binary code would introduce variable uncertainty in position, because more than one bit can change at a time, but gray code would reduce that uncertainty to being only one bit position in size.
