Abstract
Freeform surfaces are playing an irreplaceable role in both illumination design and imaging system design due to their high degrees of design freedom. Compared with traditional spherical surfaces, freeform surfaces can generate more compact and lightweight optical systems with better performance. The first part of the talk introduces the mathematical essence of illumination design and presents the Monge–Ampère equation method which may be the most advanced among the current zero-étendue methods of illumination design. The second part of the talk introduces illumination design for extended sources and presents a direct design method to achieve an accurate control of the spatial energy distribution of an extended source in three-dimensional (3D) geometry with a freeform lens. The last part of the talk focuses on freeform imaging optics design and presents an algorithm for designing freeform imaging optics with non-rational B-Spline surfaces.
