IODC 2017 illumination design problem: the centennial illuminator

For the 4th time, the International Optical Design Conference (IODC) included an Illumination Design contest. This year, the contest involved designing the illuminator to produce a “100” logo to celebrate the OSA’s 100th anniversary. The goal of the problem was to produce the highest logo luminance with greater than 30% uniformity. There were 7 entries from 2 different countries. Two different commercial optical/illumination design packages were used. The winning solution, was provided by Steve Mulder.
