    I use incremental rotary encoder to measure angle with Beaglebone. But I dont have any experience on decoding encoder.

    Can you share any rotary encoder library for Beaglebone? I need a starting point.

    These are simple incremental quadrature encoders, two square wave pulses separated by 90°.
    They show either open collector or line driver.
    Often a system will use either the two rising edges or all four edges to increase the resolution by x2 or x4.
    The technology used for anything over ~50pulses/rev is done using the Moiré technique.
