Claim:
1. An intensity distribution management system comprising: a light source situated to produce a light beam; a beam shaping system situated to receive the light beam and to produce a substantially uniform homogenized line beam propagating along an optical axis having a line axis orthogonal to the optical axis and a thickness axis mutually orthogonal to the optical axis and line axis, the homogenized line beam having a homogenized intensity profile along the line axis; a mask situated perpendicular to the optical axis so as to receive the substantially uniform homogenized line beam and to transmit selected portions of the homogenized line beam to propagate through said mask so as to be received by a target surface; and a diffusive element disposed between said mask and said beam shaping system so as to attenuate intensity ripples in a light intensity distribution of the selected portions at the target surface that are associated with the transmission of the selected portions through said mask.
