Optical Interference Coating Design Contest 2022: a black box coating and a filter for an outdoor 3D cinema challenge...

Area of Science:

• Optics and Photonics
• Materials Science
• Optical Engineering

Background:

• The Optical Interference Coating (OIC) 2022 Topical Meeting presented challenging design problems.
• These challenges included reverse engineering 'black box' optical coatings.
• Another challenge involved designing white-balanced, multi-bandpass filters for 3D cinema projection in extreme environments.

Purpose of the Study:

• To describe and evaluate the submitted designs for the OIC 2022 Topical Meeting.
• To analyze solutions for reverse engineering optical interference coatings.
• To assess filter designs for 3D cinema projection under varying environmental conditions.

Main Methods:

• 14 designers from six countries (China, France, Germany, Japan, Russia, USA) participated.
• A total of 32 designs were submitted for two distinct problems (A and B).
• Submitted designs were systematically described and evaluated based on problem requirements.

Main Results:

• The study details the variety of approaches taken by designers to solve the optical coating problems.
• Performance metrics and feasibility of the 32 submitted designs are presented.
• Insights into successful strategies for reverse engineering and multi-bandpass filter design are discussed.

Conclusions:

• The OIC 2022 Topical Meeting successfully gathered diverse solutions for complex optical coating challenges.
• The evaluated designs offer valuable insights into current capabilities in optical interference coating design.
• The findings contribute to the advancement of optical filter technology for applications like 3D cinema.
