Abstract:
1. In a reader for electro-optically reading indicia by directing a light beam along an outgoing path toward the indicia for reflection therefrom, and by detecting return light reflected along a return path from the indicia over a field of view, an arrangement for scanning at least one of the light beam and the field of view, the arrangement comprising: a) a first optical array of microlenses through which at least one of the light beam and the return light is transmitted, the first array extending perpendicular to at least one of the paths; b) a second optical array of microlenses through which said at least one of the light beam and the return light is transmitted, the second array extending parallel to the first array; and c) a drive for oscillating one of the arrays relative to the other of the arrays along opposite drive directions perpendicular to said at least one path for steering said at least one of the light beam and the return light over a scan angle.
