This analysis reveals how to achieve a desired light distribution in optical surfaces, suggesting potential applications in diverse optical systems.
We consider the inverse problem from nonimaging optics: given a source and its light distribution, find the optical surfaces that transform the light into a desired target distribution. We present models for optical systems with a parallel or point source. The surfaces (lens or reflector) are freeform. Our models are based on Hamilton’s characteristic functions and energy conservation.
