Diffraction Based MOEMS Scanner for LADAR Application
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 Contact:Amy Phillipsaphillips@optics.arizona.eduRefer to case number UA14-131
