Invention:

Researchers at the University of Arizona have developed a method of beam-steering polychromatic light by controlling the angular divergence characteristics of the beam through a pre-correction element.  The result is a collimated polychromatic beam exiting the device.

Background:

Mechanical beam steering devices for LIDAR use heavy and power-hungry gimbals and optical components making large mechanical motions.  While non-mechanical optical steering devices exist, most use electrically controlled optical diffraction elements and normally operate over a narrow wavelength band to avoid dispersion.  Others use waveguides and have small apertures.  These designs are prone to failures in harsh environments and sometimes bulky.

 

Applications:

*  Defense Industry

*  Autonomous vehicles

*  3-D Mapping

 

Advantage:

*  Larger aperture and faster reconfiguration rate

*  Accommodates polychromatic input beam
