Abstract

Freeform optics, an emerging technology, holds immense transformative potential in imaging applications. This groundbreaking technology has permeated numerous fields, providing extremely compact design for applications including AR/VR, quantum cryptography, lighting, remote sensing, medical devices, and energy research, showcasing its versatility and growing importance. Manufacturing methods have been developed such as diamond turning, additive manufacturing, or two-photon polymerization. Compared to conventional optics, a critical difficulty that limits the wide adoption of the technology, is the difficulty to generate a good initial freeform surface that can later be optimized to meet the designer requirements. Here we present a novel design method, which takes a set of analytical constraints as input and generates freeform surfaces that precisely meet these constraints as output. We address the case of a head-up display.
