A multilayer system of dielectric/metal/dielectric (D/M/D) thin films on glass substrate for energy-efficient heat mirror applications were designed theoretically and fabricated experimentally to optimize the performance. The thickness of an Ag film sandwiched between two ZnS layers of specific thickness was considered as the design parameter using IMD-Software. The measured spectral transmitta...

An instrumentation technique is developed using embedded capacitive sensors to measure the thickness and evenness of coverage of a thin layer of dielectric thermal interface material (TIM) between two substrates. The technique requires an array of sensors embedded into one substrate, with an electrically conductive opposing substrate. Local capacitance measurements are sensitive to both local b...

GdBa2Cu3O7 - δ (GdBCO) films with different thicknesses from 200 to 2,100 nm are deposited on CeO2/yttria-stabilized zirconia (YSZ)/CeO2-buffered Ni-W substrates by radio-frequency magnetron sputtering. Both the X-ray diffraction and scanning electron microscopy analyses reveal that the a-axis grains appear at the upper layers of the films when the thickness reaches to 1,030 nm. The X-ray photo...

OBJECTIVE To report normative data for retinal thickness in wild-type C57BL/6 mouse utilizing a miniature SD-OCT system. METHODS THIRTY ADULT MICE (RANGE: 3-5 months) were anesthetized and secured into the Bioptigen Spectral Domain Ophthalmic Imaging System. Right eye SD-OCT images were standardized by centralizing the optic nerve head (ONH) prior to image acquisition. Global and quadrant tot...

We present a noninvasive method for characterizing the refractive index (RI) and thickness distribution in biological tissues using a combined multiphoton microscopy (MPM) and optical coherence tomography (OCT) system. Tissue layers are distinguished by the MPM and OCT images, and the RI and thickness of each layer are determined by analyzing the co-registered MPM and OCT images. The precision ...

Spectral domain optical coherence tomography (SD-OCT) has become an established diagnostic tool for the clinical assessment of retinal pathology and its progression, in OPD setting. The aim of our study was to do in vitro quantification of relevant retinal layers to collect baseline data at different age groups, against which OCT findings can be interpreted. Thirty eyeballs (20-99 years) were u...

The underwater contact angle behavior on oxide layers of varying thicknesses was studied. These oxide layers were grown by thermally oxidizing C84400 copper alloys in N2-0.75 wt.% O2 and N2-5 wt.% O2 gas mixtures at 650 °C. Characterization of the oxidized specimens was effected using X-ray diffraction, scanning electron microscope (SEM) and contact angle goniometer. The results from the X-ray ...

[1] Rafting is one of the important deformation mechanisms of sea ice. This process is widespread in the north Caspian Sea, where multiple rafting produces thick sea ice features, which are a hazard to offshore operations. Here we present a one‐dimensional, thermal consolidation model for rafted sea ice. We consider the consolidation between the layers of both a two‐layer and a three‐layer sect...

BACKGROUND/AIMS To characterise the extension and progression of alteration of neurosensory layers following acute and chronic branch retinal artery occlusion (BRAO) in vivo using spectral-domain optical coherence tomography. METHODS In this observational case series, eight eyes with acute BRAO and nine eyes with chronic BRAO were analysed using a Spectralis Heidelberg Retina Angiograph (HRA)...

PURPOSE To use highly precise spectral-domain optical coherence tomography (SD-OCT) to determine whether there were structural abnormalities in the layers of different regions of the fovea in children with anisometropic amblyopia. METHODS Eighteen children (mean age 7.8 years old; range 5-11 years) with unilateral anisometropic amblyopia and 18 age-matched control subjects participated. Fovea...
