Lens arrays for a three-dimensional imaging system

This paper describes optical components developed for a three-dimensional imaging system based on integral photography. A variety of lens arrays with differing specifications were required and, by suitable choices and refinements to manufacturing techniques, lens arrays were developed specifically for various stages of the imaging system. Major achievements include an image transfer screen 300 nm x 300 mm with 125 mum pitch lenses formed in photoresist and high-quality replica arrays with a 100% fill factor and pitch value of 850 mum moulded from diamond-machined masters.
