    Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.

    Abstract: A switchable optical assembly comprises a switchable waveplate configured to be electrically activated and deactivated to selectively alter the polarization state of light incident thereon. The switchable waveplate comprises first and second surfaces and a liquid crystal layer disposed between the first and second surfaces. The first liquid crystal layer comprises a plurality of liquid crystal molecules. Said first and second surfaces may be curved. Said plurality of liquid crystal molecules may vary in tilt with respect to said first and second surfaces with outward radial distance from an axis through said first and second surfaces and said liquid crystal layer in a plurality of radial directions. The switchable waveplate additionally comprises a first plurality of electrodes to apply an electrical signal across said first liquid crystal layer.

    IPC: G03H1/02

    Abstract: In some implementations, an optical master is created by using a nanoimprint alignment layer to pattern a liquid crystal layer. The nanoimprint alignment layer and the liquid crystal layer constitute the optical master. The optical master is positioned above a photo-alignment layer. The optical master is illuminated and light propagating through the nanoimprinted alignment layer and the liquid crystal layer is diffracted and subsequently strikes the photo-alignment layer. The incident diffracted light causes the pattern in the liquid crystal layer to be transferred to the photo-alignment layer. A second liquid crystal layer is deposited onto the patterned photo-alignment layer, which subsequently is used to align the molecules of the second liquid crystal layer. In some implementations, the second liquid crystal layer in the patterned photo-alignment layer may be utilized as a replica optical master or as a diffractive optical element, such as for directing light in optical devices such as display devices, including augmented reality display devices.

    Abstract: In an example method for forming a variable optical viewing optics assembly (VOA) for a head mounted display, a prepolymer is deposited onto a substrate having a first optical element for the VOA. Further, a mold is applied to the prepolymer to conform the prepolymer to a curved surface of the mold on a first side of the prepolymer and to conform the prepolymer to a surface of the substrate on a second side of the prepolymer opposite the first side. Further, the prepolymer is exposed to actinic radiation sufficient to form a solid polymer from the prepolymer, such that the solid polymer forms an ophthalmic lens having a curved surface corresponding to the curved surface of the mold, and the substrate and the ophthalmic lens form an integrated optical component. The mold is released from the solid polymer, and the VOA is assembled using the integrated optical component.

    Abstract: Techniques for operating an optical system are disclosed. World light may be linearly polarized along a first axis. When the optical system is operating in accordance with a first state, a polarization of the world light may be rotated by 90 degrees, the world light may be linearly polarized along a second axis perpendicular to the first axis, and zero net optical power may be applied to the world light. When the optical system is operating in accordance with a second state, virtual image light may be projected onto an eyepiece of the optical system, the world light and the virtual image light may be linearly polarized along the second axis, a polarization of the virtual image light may be rotated by 90 degrees, and non-zero net optical power may be applied to the virtual image light.
