The thesis deals with incremental rotary encoders.
The first part briefly gives an overview of the theory on angle measurements
and describes a few chosen angle sensors, with an emphasis on the optical incremental
encoder.
The next part describes the design of a logic circuit, that, based on the two
phase shifted output signals of the encoder, detects the direction and calculates
the angle of rotation of a rotating machine part.
The third chapter addresses the realization of the circuit in LabView. The
program is then uploaded to the micro controller MyRio, manufactured by National
Instruments. As a next step a real industrial encoder is connected to it, to
test if my logic circuit works as intended.
In the last chapter of the thesis I describe how I built and tested a home-made
optical incremental encoder.
