A light projection system using white light illumination is disclosed. One embodiment provides a projection system using white light illumination. The projection system includes an illumination assembly configured to receive a white light input. A prism is configured to separate the white light input into colored light inputs, redirect the colored light inputs to respective modulators, and combine the modulated colored light inputs from the respective modulators into a white light output. The filter is configured to spatially Fourier transform the white light output to generate a filtered white light output. A projection lens assembly is configured to project the filtered white light output. 公开了使用白光照明的光投影系统。一个实施例提供了一种使用白光照明的投影系统。所述投影系统包括被配置为接收白光输入的照明组件。棱镜被配置为将所述白光输入分离成色光输入，将所述色光输入重新引导到相应的调制器，并且将来自所述相应的调制器的经调制的色光输入组合成白光输出。滤光器被配置为对所述白光输出进行空间傅里叶变换以生成经过滤的白光输出。投影透镜组件被配置为投影所述经过滤的白光输出。
