    摘要： An optical device for polarizing light including a polarization altering element operatively coupled to a light path associated with the first light coupling device and the second light coupling device is described. The optical device may further include a first waveguide portion including a first layer having parallel plane surfaces with the first waveguide portion having a first light coupling device. The optical device may also include a second waveguide portion including a second layer having parallel plane surfaces with the second waveguide portion having a second light coupling device.

    摘要： A skew mirror is an optical reflective device whose reflective axis forms a non-zero angle with the surface normal. A spatially varying skew mirror is a skew mirror whose reflective axes vary as a function of lateral position. If a spatially varying skew mirror was subdivided into many pieces, some or all of the many pieces could have a reflective axis that points in a different direction. In some variations, a spatially varying skew mirror can act as a focusing mirror that focuses incident light. A spatially varying skew mirror can be made by recording interference patterns between a phase-modulated writing beam and another writing beam or by recording interference patterns between planar wavefronts in a curved holographic recording medium that is later bent or warped.

    摘要： An optical reflective device for homogenizing light including a waveguide having a first and second waveguide surface and a partially reflective element is disclosed. The partially reflective element may be located between the first waveguide surface and the second waveguide surface. The partially reflective element may have a reflective axis parallel to a waveguide surface normal. The partially reflective element may be configured to reflect light incident on the partially reflective element at a first reflectivity for a first set of incidence angles and reflect light incident on the partially reflective element at a second reflectivity for a second set of incident angles.

    摘要： An optical device including a first layer of a total internal reflection (TIR) waveguide and a second layer of the TIR waveguide is disclosed. The second layer of the TIR waveguide may be coupled to the first layer. The second layer may include an output coupling device configured to reflect light toward an exit face of the TIR waveguide. The output coupling device may include one or more diffractive gratings. The optical device may also include an input coupling face disposed on a non-diffractive edge portion the first layer or the second layer or both the first and second layer. The input coupling face may be configured to receive image light. Another optical device may include an input coupling face disposed on a non-diffractive input coupling element. The non-diffractive input coupling element may be positioned in an optical path for directing the image light to the TIR waveguide.
