Mines and ITN joint invention enhances

GOLDEN, Colo., Jan. 18, 2012 – The development of a new circular polarization filter by a collaborative team of scientists at Colorado School of Mines and ITN Energy Systems has the potential to aid in early cancer detection, enhance vision through dust and clouds and improve moviegoer’s 3D experience.

“A wealth of knowledge is contained in the polarization information of light and accurately measuring this state of light has a number of interesting applications,” said Mines physics professor David Flammer.

When measuring the different properties of light, the naked eye can see in color but cannot differentiate between different polarizations. This new invention allows users to measure the polarization state of light quickly and efficiently and in a simple package such as a camera. 

“This is by far the easiest circular micropolarizer to fabricate, which lets us measure all of the properties of light using a simple camera,” added ITN researcher Russell Hollingsworth.

Prof. Flammer and Dr. Hollingsworth, along with Mines physics researchers Katherine Bachman, Jonathan Peltzer, Reuben Collins, and Tom Furtak recently published these findings in “Spiral plasmonic nanoantennas as circular polarization transmission filters” in Optics Express, a journal of The Optical Society.

This work was made possible by a grant from the U.S. Air Force Office of Scientific Research.
