    Abstract: According to some embodiments a method of measuring the refractive index profile of a consolidated glass body having a cylindrical surface comprises the steps of: (a) forming an image of a slit behind the glass body, (b) optionally pre-scanning the cylindrical surface of the test glass body or a reference glass body and analyzing the data within a fixed window to determine the likely location of the zero-order, un-diffracted beam while ignoring other diffracted beams; (c) optionally adjusting the optical power to improve the intensity of the data within the fixed window in order to improve the analysis; (d) predicting the trajectory of the zero-order beam through the preform based on the sampling location xi (incidence position) of the light impinging on the cylindrical surface and the location at which the zero-order beam impinges on the detector; (e) measuring the cylindrical surface of a glass body while using the estimated location of the zero-order beam and adjusted optical power to set the center of a floating window and the beam power at each measurement point; (e) determining deflection angles of the exiting zero-order beam within the floating window at each sampling location; (e) calculating the refractive index profile of glass body by utilizing a transformation function which determines refractive index at each location based upon the measured deflection angle function of the beam.

    Abstract: Display devices and antiglare layers that minimize glare and the appearance of sparkle are described. One type of display device includes a pixel substrate, having a pixel array, and an antiglare layer. The antiglare layer has a surface roughness with a spatial frequency such that a typical focal length of the antiglare layer is either at least four times larger than an optical distance between a surface of the array of pixels and the antiglare layer, or at least three times smaller than the optical distance between the surface of the array of pixels and the antiglare layer. In some embodiments, a pixel pitch of the array of pixels is less than 120 μm. In some embodiments, the antiglare layer may have a power spectral density that is elliptical, with a minor axis of the power spectral density aligned with a color direction of the array of pixels.

    Abstract: An autostereoscopic display device includes a pixelated image source, a lenticular element and an optical splitting element. The pixelated image source includes a matrix of pixels and dark regions. The lenticular element includes a plurality of cylindrical lenses and is disposed adjacent the pixelated image source such that each of the cylindrical lenses extends over a substantially equal area of dark regions.

The first parallel lines and the second parallel lines are parallel with the cylindrical lenses. The first parallel lines extend over three neighboring sub-pixels within each of the rows. The second parallel lines extend over three neighboring sub-pixels within each of the rows.

    Abstract: Pressure-sensing touch systems and methods are disclosed for sensing the occurrence of a touch event based on pressure applied at a touch location. The touch system includes a light-source system and a detector system operably adjacent respective input and output edges of a waveguide. Pressure at a touch location on the waveguide gives rise to a touch event causes the waveguide to bend or flex. The waveguide bending causes a change in the optical paths of light traveling by FTIR, causing the light distribution in the output light to change. The changes are detected and are used to determine whether a touch event occurred, as well as the time-evolution of the touch event. The changes in the output light can include polarization changes caused by birefringence induced in the waveguide by the applied pressure applied. Various detector configurations are disclosed for sensing the location and pressure of a touch event.
