| 英文摘要 | A modular illumination system is capable of producing a light beam having a wide field of view - e.g., in excess of ninety degrees - while maintaining a high collection efficiency as well as a high degree of beam homogeneity. The illumination system comprises an elementary unit (300) having a linear array of light sources (306). Light from the light sources (306) is collimated using a corresponding array of catadioptric lenses (308), and the collimated light is homogenised in the tangential plane using two cylindrical lens arrays (304a, 304b) set in tandem to one another. The homogenised light is then collimated in the sagittal plane using a cylindrical lens (302) that is set perpendicular to the lenses of the two cylindrical lens arrays (304a, 304b) to yield a wide linear beam. To produce an area beam, the linear array of light sources (306) can be replaced with a two-dimensional array, and the cylindrical lenses (304a, 304b) can be replaced with spherical lenses. |
