Abstract:
1. An arrangement for uniformly illuminating indicia to be imaged and electro-optically read, comprising: a solid-state imager having an optical axis, for capturing light over a field of view from the indicia; an illuminator for emitting illumination light, according to an intensity profile, toward the indicia; a diffuser for diffusing the illumination light en route to the indicia, the diffuser including a plurality of diffusing elements adjacent the illuminator; and wherein the illuminator includes a plurality of illumination light sources spaced apart from one another; and wherein each illumination light source has a source axis along which the illumination light of greater intensity is emitted, and wherein each diffusing element made of diffusing material is elongated and has an end face adjacent a respective illumination light source and through which the illumination light of greater intensity along the source axis enters the respective diffusing element.
