Abstract: A display article is described herein that includes: a substrate comprising a thickness and a primary surface; a textured surface region; and an antireflective coating disposed on the textured surface region. The textured surface region comprises structural features and an average texture height (Rtext) from 50 nm to 300 nm. The substrate exhibits a sparkle of less than 5%, as measured by PPD140, and a transmittance haze of less than 40%, at a 0˚ incident angle. The antireflective coating comprises alternating high refractive index and low refractive index layers. Each of the low index layers comprises a refractive index of less than or equal to 1.8, and each of the high index layers comprises a refractive index of greater than 1.8. The article also exhibits a first-surface average photopic specular reflectance (%R) of less than 0.3% at any incident angle from about 5˚ to 20˚ from normal at visible wavelengths.

Abstract: The systems and methods include generating polarization-switched (PS) detector and reference signals using a polarization switch controlled by a digital control signal generated by digital input/output card. A gain adjustment is performed on the PS detector and reference signals to define gain-adjusted detector and reference signals. The digital control signal is used to synchronize the gain-adjusted PS detector and reference signals to define gain-adjusted synchronized PS detector and reference signals each having respective steady-state portions. The steady state portions are used to define a measurement signal. The measurement signal is then used to calculate a stress-based characteristic of the sample being measured. The sample can be moved continuously or discretely through different measurement positions, which are synchronized with the operation of the polarization switch using the digital control signal.
