发明名称 COMPACT ILLUMINATION MODULE FOR HEAD MOUNTED DISPLAY
摘要 <p>An illumination module includes a light source to output lamp light and a mixing light guide having a substantially rectangular cross-section. The mixing light guide includes a spatial homogenization section and an emission section. The spatial homogenization section includes a first end coupled to receive the lamp light having a first cross-section profile from the light source and a second end to deliver the lamp light with a second cross-section profile substantially conforming to the substantially rectangular cross-section of the mixing light guide. The emission section is adjacent to the second end. The emission section includes an emission surface through which the lamp light is emitted with a substantially uniform intensity profile. The emission surface faces a different direction than an input surface of the first end through which the lamp light is received into the mixing light guide.</p>
