Abstract: A solid state illumination system is provided for image projection. Red, green and blue light is generated using a blue laser light source and phosphor emissions. The red, green and blue light is passed by TIR or TRIR elements of red, green and blue light channels of an X-cube prism structure for separate modulation by different spatial light modulators. The modulated red, green and blue light is passed by the TIR or TRIR elements into the X-cube and combined into a combined modulated RGB image forming light stream for image formation via projection optics onto a target imaging surface.

Abstract translation: 提供固态照明系统用于图像投影。 使用蓝色激光光源和磷光体发射产生红色，绿色和蓝色光。 红色，绿色和蓝色光通过X立方棱镜结构的红色，绿色和蓝色光通道的TIR或TRIR元件，以通过不同的空间光调制器进行单独调制。 调制的红色，绿色和蓝色光被TIR或TRIR元件传递到X立方体，并组合成组合的调制RGB图像形成光流，用于通过投影光学器件到目标成像表面上的图像形成。
