Abstract

The optical flux partition method is utilized to design a reflective mirror that can provide both good uniformity in illumination and high directivity. Compared with other schemes, this method features directness, fast convergence, and wide applications. For the case under study, the uniformity of the illumination can reach 80%, which is good enough for common usage, and the directivity diverging angle can be less than 3 $^{\circ}$ .
