Official abstract text for this publication.
An apparatus and method for providing pixelated occlusion is disclosed. The apparatus includes a display, a unitary and transmissive optical component, and a contact lens. The display provides a display image. The unitary reflective and transmissive optical component receives the display image and forms a reflected display image having a first polarization and receives a scene image and forms a transmitted scene image. The contact lens forms a combined image including the reflected display image and the transmitted scene image. The pixelated display includes one or more occluding pixels having a second polarization with the first polarization substantially orthogonal to the second polarization. The pixelated display is included anterior to the unitary and reflective optical component.
Opening claim text (preview).
What is claimed is: 1. An apparatus comprising: an eyewear frame, a spectacle lens in the eyewear frame, the spectacle lens having a scene image optical axis when worn by a user that is aligned with a user's visual optical axis, a scene image to be received substantially along the scene image optical axis; an emissive display coupled to the eyewear frame, the emissive display having a display optical axis to intersect the user's visual optical axis, the emissive display to form an emissive display image; and a unitary reflective and transmissive optical component coupled to the eyewear frame, the unitary reflective and transmissive optical component having a complementary transmitted optical axis and a complementary reflected optical axis, the complementary transmitted optical axis substantially aligned with the user's visual optical axis and the complementary reflected optical axis substantially aligned with the display optical axis, the unitary reflective and transmissive optical component to reflect and polarize the emissive display image along the user's visual optical axis, and the unitary reflective and transmissive optical component to transmit and polarize the scene image along the visual optical axis, the emissive display to emit a unique color having a unique wavelength, and the unitary reflective and transmissive optical component to include a spectral filter including an absorptive notch filter having a center wavelength substantially equal to the unique wavelength. 2. The apparatus of claim 1 , wherein the absorptive notch filter has a width of between about five and about thirty nanometers. 3. The apparatus of claim 1 , wherein the center wavelength is within about five and about twenty nanometers of the unique wavelength.
