First Claim
Patent Images
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.

Abstract
Apparatus and associated methods relate to an array of independently-controllable laser diode bars configured to scan a linearly-structured beam of light upon a scene. Each of the independently-controllable laser diode bars is distributed along a common axis. Each of the independently-controllable laser diode bars is configured to emit a beam of light in an emission direction orthogonal to the common axis. Each of the independently-controllable laser diode bars can be energized in a sequence, thereby scanning the scene in the direction of the common axis.
