摘要： A scanning apparatus and method, the apparatus comprising a light transmitter, a mount for supporting the light transmitter located remotely from its exit tip, a drive for driving the light transmitter to vibrate resonantly in a first direction and to vibrate non-resonantly in a second direction orthogonal to the first direction, and a synchronizer for synchronizing vibration of the light transmitter in the first and second directions so that the exit tip of the light transmitter executes a scan pattern. The drive applies a driving force to the light transmitter between the mount and the exit tip.
