摘要： An optical element includes a first layer (220), a second layer (240), and a fluid (230). A first surface (211) of the first layer is configured to change hydrophobicity in response to incoming activation light. Absorbing molecules in the fluid are repelled or attracted to the first surface in response to the hydrophobicity of the first surface.

摘要： An optical element is provided. The optical element includes an optical film including a birefringent material having a chirality. Optically anisotropic molecules of the birefringent material disposed adjacent a first surface of the optical film are configured with a first pretilt angle in a range of greater than 10° and less than 80°, or in a range of greater than -80° and less than -10°. Optically anisotropic molecules of the birefringent material disposed adjacent a second surface of the optical film opposing the first surface are configured with a second pretilt angle in the range of greater than 10° and less than 80°, or in the range of greater than -80° and less than -10°.

摘要： An optical device includes a light source and a polarization selective optical element. The polarization selective optical element includes a stack of a plurality of cholesteric liquid crystal layers. The plurality of cholesteric liquid crystal layers includes a first cholesteric liquid crystal layer with liquid crystal molecules arranged in a first helical configuration having a first pitch range for light of a first wavelength range and a second cholesteric liquid crystal layer with liquid crystal molecules arranged in a second helical configuration having a second pitch range for light of a second wavelength range. The second wavelength range is different from the first wavelength range.

摘要： A device includes one or more light guides. The device also includes a first in-coupling element configured to couple a first light having a first input field of view ("FOV") into a first light guide, and a second in-coupling element configured to couple a second light having a second input FOV into a second light guide. The device also includes a first out-coupling element configured to couple the first light out of the first light guide as a first output light having a first output FOV, and a second out-coupling element configured to couple the second light out of the second light guide as a second output light having a second output FOV substantially non-overlapping with the first output FOV. A combination of the first output FOV and the second output FOV is larger than at least one of the first output FOV or the second output FOV.

摘要： An optical device is provided. The optical device includes a first optical element configured to output an elliptically polarized light having one or more predetermined polarization ellipse parameters. The optical device also includes a second optical element including a birefringent material with a chirality, and configured to receive the elliptically polarized light from the first optical element and reflect the elliptically polarized light as a circularly polarized light.

摘要： A display system includes a source of unpolarized image light, and a stack of polarization-selective optical elements operable to switchably convert the unpolarized image light into two orthogonally polarized light beams, each of which being switchable in at least one beam characteristic. An output polarizer selects one of the two orthogonally polarized light beams for providing to a user. A depolarizer may be disposed between an electronic display emitting polarized light and the stack. The depolarizer may be in the form of an LC bilayer with randomized in-plane optic axis.

摘要： A device includes a light source configured to generate an image light. The device also includes a lens assembly coupled with the light source. The lens assembly includes a mirror configured to transmit a first portion of the image light and reflect a second portion of the image light. The lens assembly also includes a reflective polarizer including a birefringent medium with a chirality and configured to substantially reflect the first portion of the image light output from the mirror as a polarized light having a predetermined handedness toward the mirror. The lens assembly further includes a lens disposed between the mirror and the reflective polarizer and configured to provide an optical power to the image light.

摘要： A transferrable thin-film optical device and a head-mounted display are provided. A transferrable thin-film optical device comprises a thin-film layer providing at least one predetermined optical function. The thin-film layer is configured to be removably attached to a substrate, such that a molecular pattern for the at least one predetermined optical function of the thin-film layer is preserved post removal.

摘要： An optical device for a head-mounted display device includes a first partial reflector and a second partial reflector positioned relative to the first partial reflector so that the second partial reflector receives first light transmitted through the first partial reflector and reflects at least a portion of the first light toward the first partial reflector as second light. At least a portion of the second light is reflected by the first partial reflector as third light, and at least a portion of the third light is transmitted through the second partial reflector. At least one of the first partial reflector or the second partial reflector includes a reflective holographic element.
