Abstract
A system for forming a homogenized illumination line which can be imaged as a low-speckle line is disclosed. The system includes a laser configured to emit a collimated laser beam; and an illumination-fan generator that includes one or more linear diffusers. The illumination-fan generator is arranged and configured to (i) receive the collimated laser beam, (ii) output a planar fan of diffused light, such that the planar fan emanates from a light line formed on the distal-most one of the one or more linear diffusers, and (iii) cause formation of an illumination line at an intersection of the planar fan and an object.
