A 3D imaging system includes a camera to capture visible images, and a MEMS device with a scanning mirror that sweeps a beam in two dimensions. Actuating circuits receive angular extents and offset information and provide signal stimulus to the MEMS device to control the amount and direction of mirror deflection on two axes. The scan angle and offset information may be modified in response to camera properties.
