1. A system for projecting a linear beam of light on a distant object, the system comprising:

  • an array of independently-controllable laser diode bars distributed along a common axis, each of the independently-controllable laser diode bars configured to emit a beam of light in an emission direction orthogonal to the common axis, the emitted beam of light diverging about the emission direction at a first divergence angle in the plane including the emission direction and a fast-axis direction, and diverging about the emission direction at a second divergence angle in the plane including the emission direction and a slow-axis direction, wherein the second divergence angle is less than the first divergence angle.
