ABSTRACT:
There is disclosed a method and system for controlling the optics of a coherent light source impacting a three dimensional defined volume. The system uses a scanner to time and spatially position the coherent light. The divergent light beam output of the scanner is then placed through positive and negative lenses to narrow the beam waist while also increasing the divergence angle of the beam. Provision is made to abate the divergence angle so that the light, as it impacts the defined volume, will not continue to diverge, creating a skewed image within the volume.
