Modern optical encoders are divided into two types: incremental and absolute systems. Both systems are capable of high-accuracy and high-resolution operation. Both are available for linear and rotary axes across a variety of industries. So how does a system designer choose the right encoder for their application? Ultimately, the correct choice of encoder depends on the application, but there are several function and performance differences that need to be considered before the system designer can make the correct choice.
