MULTI-SPATIAL LIGHT MODULATOR IMAGE DISPLAY PROJECTOR ARCHITECTURES USING SOLID STATE LIGHT SOURCES

摘要

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.

1. A method for projecting images, comprising:
generating red, green and blue light using a blue laser light source and phosphor emissions; introducing the red, green and blue light to respective first, second and third TIR or TRIR elements of corresponding respective red, green and blue light channels of an X-cube prism structure; separately modulating the introduced red, green and blue light by respective first, second and third spatial light modulators of the corresponding respective red, green and blue light channels; and passing the separately modulated red, green and blue light via the respective first, second and third TIR or TRIR elements into the X-cube prism structure and combining them with the X-cube prism structure into a combined modulated RGB image forming light stream for image formation via projection optics onto a target imaging surface.
