  • Infrared Wire Grid Polarizers -Metrology and Modeling
    the SWIR to LWIR using a combination of FTIR and dispersive spectrometers, as well as laser-based light sources. The WGP structures were analyzed using SEM, FIB, and STEM techniques and optical data was derived from IR VASE, transmission, and reflectance measurements. Modeling of device performance
  • Designing Atmospheric-Pressure Plasma Sources for Surface Engineering of Nanomaterials
    . It is important to note that Re{K(o)} can take both. positive and negative values based on the sign of Eq. (6). When the particle is more polarizable than the medium, the. particle will move toward regions containing the highest. gradient of the inner product of the electric field (positive. DEP
  • Low Coherence Vibration Insensitive Fizeau Interferometer
    that is substantially normal to the optical axis of the cavity. Additionally, stray light interference is substantially reduced due to the source's short coherence. An expression for the fringe visibility on-axis is derived and compared with that of a standard Fizeau.
  • Identification and Suppression of Thermal Reflections in Infrared Thermal Imaging
    Thermal reflections are a common source of problems in interpreting infrared (IR) thermal images. In particular, atomically smooth surfaces like glass, metals, or wet surfaces, and also brick and concrete, may easily give rise to reflections of infrared radiation from often uncared sources
  • Pixelated Phase-Mask Dynamic Interferometer
    with a wide variety of interferometer front ends, and with virtually any light source including white-light. Phase-stepping interferometry is an established method for measuring a variety of physical parameters ranging from the surface figure of mirrors to the displacement of solid objects.1 Phase-shift
  • Complementary LED Drive
    or sources a single LED. To drive more than one, a high I/O count is required. In order to reduce I/O requirements, LED's are multiplexed in a matrix (as found on a keyboard). The complementary LED drive method proposes to implement even more LEDs while using fewer I/O. LEDs are polarized and can only
