    • Light sources and methods for spreading a beam of electromagnetic radiation. The light sources include a scattering element with an outlet and an angular-selective element with an inlet spatially disposed between the outlet of the scattering element and an electromagnetic radiation source. The beam enters the inlet traveling in a direction of propagation and propagates through the beam spreader to the outlet for transmission from the outlet. The scattering element includes a scattering medium configured to scatter the electromagnetic radiation in the beam to provide a two-dimensional spatial distribution for intensity that is substantially uniformly across the outlet. The angular-selective element is configured to reflect a majority of the electromagnetic radiation of the first beam scattered by the scattering medium in a direction opposite to the propagation direction and reaching the angular-selective element.
    • 用于扩展电磁辐射束的光源和方法。 光源包括具有出口的散射元件和角度选择元件,入射空间地设置在散射元件的出口和电磁辐射源之间。 梁进入沿传播方向行进的入口,并通过射束撒布机传播到出口,以从出口传播。 散射元件包括散射介质,其被配置为将光束中的电磁辐射散射以提供基本上均匀地穿过出口的强度的二维空间分布。 所述角度选择元件被配置为反射散射介质散射的第一光束的大部分电磁辐射沿与传播方向相反的方向并且到达角度选择元件。
