1. An angle- and wavelength-multiplexed holographic optical element (“

  • HOE”

    ) comprising;

    at least one layer of holographic material that includes;

    a first set of wavelength-multiplexed holograms, wherein each respective hologram in the first set of wavelength-multiplexed holograms is responsive to light of a respective wavelength and unresponsive to light of other wavelengths, and wherein all of the holograms in the first set of wavelength-multiplexed holograms are responsive to light that is incident thereon with an angle of incidence that is within a first range of angles of incidence and unresponsive to light that is incident thereon with an angle of incidence that is outside of the first range of angles of incidence; and

    a second set of wavelength-multiplexed holograms, wherein each respective hologram in the second set of wavelength-multiplexed holograms is responsive to light of a respective wavelength and unresponsive to light of other wavelengths, and wherein all of the holograms in the second set of wavelength-multiplexed holograms are responsive to light that is incident thereon with an angle of incidence that is within a second range of angles of incidence and unresponsive to light that is incident thereon with an angle of incidence that is outside of the second range of angles of incidence, the second range of angles of incidence different from the first range of angles of incidence.
