A three dimensional image projector stabilization circuit including providing a first input device, a second input device, and a sensor for determining the rotational speed of the second input device. A control device for controlling the rotational speed of the second input device and a phase locked loop (PLL) are also provided. A phase reference signal is created based on the signal rate of the first input device. A phase signal is created based on the rotational speed of the second input device as it is measured by the sensor. The PLL compares the phase reference signal and the phase feedback signal to determine whether the first input device and the second input device are synchronized. A signal is sent to the control device for the second input device to change the rotational speed of the second input device in response to determining that the first input device and the second input device are not synchronized. |
