| 摘 要： | 研究了用多角形棒状透镜产生高均匀性正方形和圆形照明的最佳结构参量.结果表明,对于正方形棒状透镜,输出端的照明均匀性随透镜的长度振荡变化,在某些特定长度达到极小值.对于圆形照明面积,比较了从三角到八角的六种多边形.利用三角形积分透镜可以获得最佳的照明均匀性,但光能利用率相对较低,六角形积分透镜可同时获得较高的照明均匀性和光能利用率.

| Abstract: | A effective way to transfer a symmetrical spot light to uniformity illumination by using polygon rod integrating lens was proposed.A detail study has been carried out to obtain square and circle uniform illumination by polygon rod lens.In some specific length,lenses have best uniformity performance.Triangle and hexangular lens are good choice for circle illumination.Triangle lens is best in uniformity,and hexangular lens has better light collecting efficiency.The illumination uniformity is affected sensitively by light source position offset from optical axis. |
