| 英文摘要 | Techniques of providing illumination to a head-mounted display (HMD) involve providing off-board illumination apart from the HMD. An off-board illumination unit delivers the illumination to the HMD via optical fibers. The optical fibers are lightweight and do not restrict motion of a user. Because the power source is less restricted, the off-board illumination unit provides flexibility in the hardware used to generate the illumination. For example, the illumination unit may use red, green, and blue narrow-band diode lasers. Further, by controlling modes in the fiber and providing additional light-guiding hardware, the angles at which light strikes LCD pixels may be largely restricted to certain specified angles. Restricted angles of incidence enable the use of fast-switching liquid crystals without degrading the image quality. Such a restriction allows for high-resolution imaging using rapid switching of the liquid crystal which enables very low latencies. |
