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.
