摘要： Described is an optical compensator device that can maintain a high degree of performance in the demanding environment of projection display. A mounting process involves using a sealant between optically clear glass or ceramic substrate and low elastic polymer retarder film. The sealant may mitigate or prevent the degradation of the retarder film by acting as an oxygen barrier that seals the substrate and increases the lifetime of the device in high luminance.

摘要： An achromatic polarization switch (APS) acts on linear polarized light to provide orthogonal polarized output states over a range of visible wavelengths. In a first switching state, the APS is operable to pass light of a first polarization state therethrough. In a second switching state, the APS is operable to transform light passing therethrough to a substantially orthogonal second polarization state. Used in conjunction with orthogonal analyzing eyewear, left and right eye images are time-sequentially modulated in orthogonal polarization states by the APS to yield a stereoscopic 3D image sensation.

摘要： A direct view display provides a light modulating panel and a backlight including first and second sets of spectral emitters. The first set of spectral emitters generate a first light bundle and the second set of spectral emitters generate a second light bundle. Several modes of operation may be provided including (1) an advanced 2D mode, (2) an enhanced color gamut mode employing simultaneous illumination of the first and second set of spectral emitters, (3) a privacy screen mode, (4) a channel multiplexed mode, and (5) a stereoscopic image mode. The latter three modes utilize the first and second set of spectral emitters to alternately illuminate a portion of the light modulating panel. Images and representations generated by the direct view display operating in the latter three modes are viewed using appropriate eyewear having filters with passband characteristics to transmit the respective light bundle.

摘要： The selective filtering of light by polarization interference may be used to enhance vision and/or protect eyes from harmful light rays. For example, such filtering may be used in sunglasses, color corrective eyewear or protective eyewear. The selective filtering of incident light may provide any desired spectral transmission (including visible light and light not visible to the eye) and is performed by a pair of polarizing elements that sandwich a retarder stack. The filtering structure may be formed by multi-layer polarizing structures and may be formed by fabricating sheet laminates that are die cut to form inexpensive laminates. The laminates may be flat or curved in one (e.g., wrap-around) or more dimensions.

摘要： Chemically-bonded laminated polymer achromatic polarization devices, such as circular polarizers, are disclosed for use in optical disc (e.g., CD/DVD) pickup heads. Chemically-bonded laminated polymer achromatic polarization devices have the benefit of providing stable retardation and optic axis over an extended wavelength range, thereby ensuring orthogonal polarization in double-pass for two or more laser wavelengths. Moreover, the chemically-bonded laminated polymer achromatic polarization devices can be symmetric in construction, such that there is no specific input and output side. This alleviates the need to produce geometries that prohibit inversion of the part when installed in the system. Manufacturing processes that produce chemically-bonded laminated polymer achromatic polarization devices, with high light efficiency, durability and robust performance in a variety of environmental conditions are disclosed.

摘要： The disclosed technique employs a process for mating polarizing wafers to clear lenses using a high-yield bonding process. A thermoformed polarizing wafer is bonded to a clear lens of similar curvature via a solvent bonding process. In one embodiment, a system includes a translation stage configured to press a first lens to a second, with a solvent therebetween, such that a portion of the first lens initially contacts a portion of the second lens. An alignment fixture holding the second lens conforms to the curvature of the second lens, and a deformable sheet mounted proximate to the alignment fixture flexes in response to the force so that either of the first or second lenses conforms to a curvature of the other, and so that the pressure of the first lens against the second lens presses the solvent radially outward to the perimeter of the second lens to bond the first lens to the second lens.
