IODC was held on 09 – 13 July 2017 at the Denver Marriott City Center, Denver, Colorado United States. This was a joint meeting with OSA managing the meeting and SPIE publishing the proceedings. Additional sponsors included Synopsys, Photon Engineering, Optimax and American Elements.
2016 was the 100th anniversary of the Optical Society of America – its Centennial year. To celebrate this, the 2017 IODC Lens Design Problem (announced in 2016) had a centennial theme. The problem was to design a lens which includes a “100 lens” somewhere within the overall lens to commemorate OSA’s 100th anniversary. The 100 lens comprises a 10 mm thick flat plate and two ball lenses 40 mm in diameter. There was no limit to the number of lenses before or after the 100 lens, but additional optical elements within the 100 lens were not allowed.
In keeping with the centennial theme the illumination design problem was to create an emissive ‘100’ logo for the anniversary. Using two planar Lambertian disc sources (radius=1) that emit into the positive (+z) hemisphere to create the numerals ‘0’, a 90% reflective disc covers each center of the two disc sources. Source light was to be reflected by the discs into negative (-z) hemisphere. The goal was to couple that reflected light into the ‘1’ to maximize the logo luminance while keeping the average luminance of all three numerals the same.
