The 2014 International Optical Design Conference (IODC) was held June 22-26, 2015 in Hawaii. It was co-sponsored by OSA and SPIE. The IODC conference chairs were Mariana Figueiro, Scott Lerner, Julius Muschaweck & John Rogers.
The IODC traditionally includes one or more lens design and illumination design problems for members of the optical design community to consider.
The lens design problem was titled The Cinderella Lens. In the Cinderella story, Cinderella’s two stepsisters cannot squeeze their big feet into the glass slipper, no matter how hard they try; however, Cinderella’s foot fits the glass slipper perfectly. The problem was to design a Cinderella lens. You are provided with ten lens blanks, each 100 mm in diameter, 30 mm thick, and flat on both sides. All the lens elements in the Cinderella lens must be fabricated from these ten lens blanks. Just as Cinderella’s foot fit the glass slipper, each element of the Cinderella lens must fit inside one of the lens blanks provided.
In the illumination design problem you have recently come across the guts of a 35-mm film projector and a roll of the 1950 Walt Disney “Cinderella” movie (an Academy format film), and have added it to your box of optical knick-knacks in your lab. There is no working lamp for this projector, but it has working mechanics and a Cooke Triplet projection lens. Your optical tool box includes lots of unique components, which are listed below. It also includes a bunch of light sources (Lambertian emitters and lasers) which are also specifically defined below. Your task is to build an illuminator for the projector to create an image of the film. You can use anything in the tool box, but you cannot add to the toolbox, and you do not need to use everything in the toolbox. The goal is to produce the brightest screen image with some specific constraints listed below.
