New Findings from University Carlos III of Madrid in the Area of Materials Research Reported

June 24, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Materials Research. According to news reporting out of Madrid, Spain, by VerticalNews editors, research stated, "Until now, several attempts have been made to obtain axicons by using liquid crystals. Previous results had always a considerable deviation from the linear response and the resulting aperture is square."

Our news journalists obtained a quote from the research from the University Carlos III of Madrid, "In addition, classical fabrications methods are expensive and only produce fixed phase profiles. In this study, a novel structure to obtain tunable axicons with a perfect conical shape and a circular aperture is proposed and theoretically studied. The proposed optical device is based on nematic liquid crystal and phase shifted electrical signals. A simulation program consisted of Finite Elements Method to solve the voltage distribution combined with the Frank-Oseen equation to solve the molecular position of the nematic liquid crystal is employed. This device is totally reconfigurable by using low voltage signals."

According to the news editors, the research concluded: "The focus depth and the position of this one can be controlled electrically."
