Abstract
Apparatus for generating a line-beam includes a diode-laser bar, a linear micro-lens array, and a plurality of lenses spaced apart and arranged along an optical axis. The linear micro-lens array and the lenses shape laser-radiation emitted by the diode-laser bar to form a uniform line-beam in an illumination plane. The lenses project a far-field image of the diode-laser bar onto an image plane proximate to the illumination plane. The diode-laser bar is rotated from parallel alignment with the linear micro-lens array for providing uniform line-beam illumination over a range of locations along the optical axis.
