Figure 1 shows the circuit with the simple and basic design in order to achieve position control, it uses a pair of photodiodes connected in parallel with the the fast response time. Thus it achieves a system with small number of components, it has high reliability, accuracy and repeatability under clearly defined work environment. The circuit shown as the Figure 1 uses a power op amp to combine differential output of a pair of photodiodes, and it drives the direction of motor rotation to the right until the two photoelectric currents are equal, thus it achieves position control order.
