摘要： A scanning apparatus and method, the apparatus comprising: a light transmission means (90) having an exit tip; first and second drive means (92,94) for resonantly driving the light transmission means (90) in orthogonal directions; wherein the first and second drive means (92,94) are operable to move the tip in an elliptical pattern while varying the eccentricity of the elliptical pattern, whereby a portion of the elliptical pattern having a centre on the minor axis of the elliptical pattern approximates—at least in appearance—a raster pattern.

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.
