Two methods are proposed, using symmetric mirror combinations, which provide significant image plane irradiance improvement for line scanning applications employing lens arrays. The methods generally use mirrors to cause the generation of multiple apparent source or object lines in object space, within the field angle of the gradient index lens array, and a similar set of mirrors in image space to combine the multiple images to a single image line.
