    Tips: Angular position detection of stepper motor
    As for angular position of stepper motor, it is generally detected through two methods: using rotary transformer and optical encoder. Absolute optical encoder is a non-contact position feedback and measurement element, featuring simple structure, high reliability, high resolution, high precision, small volume and light weight.
    By connecting coded disc with mechanical axis, angle coding can be directly output, then the coding is input into the SCM. The angle value can be obtained through decoding without any adjunct circuit, like A/D switching and amplifying filter, etc..
    Stepper motor control system with optical encoder is comprised of stepper controller, driver and stepper motor. The feedback on output of optical encoder is given to the control circuit. Then, the circuit adjusts the angle of stepper motor according to the feedback output.
