摘要：

Computer ray tracings were performed on four brightness enhancement configurations. Results for the area demagnification ratio of the four enhancement configurations are given. A very high area demagnification ratio is found for the spherical enhancer: a brightness gain of as much as 1000 could be achieved in a single stage with existing technologies.
