Where can you find a gathering of people who share the same interests in optical design, want to further developments and research, and compete in solving challenging problems? We’re talking about the International Optical Design Conference (IODC), which was held in person this year in Quebec City, Quebec, Canada, on June 4-8.

Networking and IODC Significance

IODC, held every four years, is the “Olympic games of optical design,” according to Henning Rehn, one of the meeting chairs. IODC was co-located with the . To start off the week, a welcome breakfast on Monday provided a good time to network with colleagues in the industry.

“IODC is a special conference that brings together the optical community and provides a ‘snapshot in time’ of what has happened over the last four years,” said Dr. Bill Cassarly, one of the conference organizers.

Design Challenges and Winners

This year, the  required a solution to reattach the unicorn’s horn to save the Kingdom of Lambert. Designs needed to be modeled in single commercial software package and follow specified criteria. John Hygelund, a student from the University of Arizona, was the winner of this challenge.

The , also called the Shafer Cup Competition, challenged designers to model a maximum-etendue lens with diffraction-limited image quality over the field of view at 550 nm and yet have bad on-axis image quality at 540 nm when evaluated at the same image location. The coveted Shafer Cup was awarded to the entry with the highest merit function, which was submitted by Arnaud Davenel of Safran in France. The student winner for this year’s Shafer Cup lens design problem was Guillaume Allain from University of Laval.

“I want to recognize the tremendous effort of the winners who created some really complex systems,” said Henning, who was also a member of the Illumination Guild. The Illumination Guild creates the illumination design challenge for every IODC.  We heard that Georg Nadorff from Garmin had great fun trying to come up with a solution using Chat GPT. The good news is that we still need the expertise of human optical designers to solve these optical design problems!

六合彩直播开奖 and Industry Presentations

IODC included many inspiring talks and great discussions. Following is a summary of presentations by 六合彩直播开奖 staff and selected industry colleagues.

• Hybrid Fresnel-Diffractive Lens Design for Virtual Reality. By Yang Zhao, Meta Platform, Reality Labs Research. Yang designed and prototyped a hybrid lens with a high-index Fresnel lenses made of ZnS and a diffractive lens made of liquid crystal polymer for virtual reality displays. 
  
  
• Improving Weight and Imaging Performance of a Very Fast f/0.75 Lens Using Optical Co-Design. By Marie-Anne Burcklen, Angenieux and Thales. Marie-Anne described how using a surrogate merit function that combines the classical merit function with weighted constraints that enforces MTF and PSF invariance is fast to optimize and provides a good solution when deconvolution is used in post processing.

Community and Partnerships

六合彩直播开奖 and other companies exhibited at the conference. 六合彩直播开奖 staff passed out IODC 2023 commemorative t-shirts, a tradition for Optical 六合彩直播开奖 to give out at every IODC. This year’s shirt featured the skyline of Quebec City and highlighted that we are celebrating 60 years in optics!

Nick Takaki, a past Kidger Scholarship winner and R&D engineer at 六合彩直播开奖, sums up the entire experience:

“IODC is a vibrant gathering of global authorities in optical design, exemplifying the passion, camaraderie, and expertise of this community. Attending, presiding, and engaging in after-hours discussions were thrilling experiences that leave me excited to be a part of the future of optical design.”
