Flexible, low-loss, large-area multilayer plasmonic optical metasurfaces are demonstrated and analyzed that provide wavelength-selective reflectance >95% and transmittance <1% with low absorption and robustness to variation in angle of incidence and polarization. These characteristics are shown to be insensitive to vertical misalignment between layers, and defects within individual layers. Anal...

PURPOSE To quantify bleaching-induced changes in fundus reflectance in the mouse retina. METHODS Light reflected from the fundus of albino (Balb/c) and pigmented (C57Bl/6J) mice was measured with a multichannel scanning laser ophthalmoscopy optical coherence tomography (SLO-OCT) optical system. Serial scanning of small retinal regions was used for bleaching rhodopsin and measuring reflectance...

Optical spectroscopy techniques such as differential reflectance and transmittance have proven to be very powerful techniques for studying 2D materials. However, a thorough description of the experimental setups needed to carry out these measurements is lacking in the literature. We describe a versatile optical microscope setup for carrying out differential reflectance and transmittance spectro...

Porous silicon (PS) multilayer stacks were developed for their use as interference filters in the visible range. The optical behavior of these structures was previously simulated by the use of a computational program, from which the optical constants and thickness of the individual PS layers were determined. The possibility of using these structures as biosensors has been explored, based on the...

In this data article, morphological and optical data of AgNW encapsulated between ITO layers are presented to get insights into our article (DOI:10.1016/j.solmat.2016.04.038; Hong-Sik Kim, Pankaj Yadav, Malkeshkumar Patel, Hyunki Kim, Kavita Pandey, Joondong Kim, 2016) [1]. SEM images for the formation of AgNWs networks by number of spin coating are also presented. SEM photographs showing the s...

Dielectric multilayer coatings exhibiting steep reflectance in an extremely narrow transition zone, highly sensitive to any variations of layer refractive indices and therefore suitable for studying the nonlinear properties are produced and characterized. Increase of reflectance at growing intensity reveals the presence of the optical Kerr effect. A new method calculating intensity dependent sp...

18 The interannual variability of cloud properties in a tropical subsidence area (South 19 Atlantic Ocean) is examined using 23 years of ISCCP cloud fractions and optical depths, 20 complemented with ISCCP/Meteosat visible reflectance and a four-years comparison with 21 CALIPSO-GOCCP products. The mean seasonal cloud properties are examined in the area, as 22 their interannual evolution. Circul...

A reflectance confocal scanning laser microscope (rCSLM) operating at 488-nm wavelength imaged three types of optical phantoms: (1) 100-nm-dia. polystyrene microspheres in gel at 2% volume fraction, (2) solid polyurethane phantoms (INO Biomimic(TM)), and (3) common reflectance standards (Spectralon(TM)). The noninvasive method measured the exponential decay of reflected signal as the focus (z(f...

A short-separation, optical reflectance probe has been developed to assist the neurosurgeon in functional neurosurgery for accurate localization of the surgical target. Because of the scattering nature of tissue, the optical probe has a "Look Ahead Distance" (LAD), at which the measured optical reflectance starts to "see" or "sense" the underlying brain structure due to the difference in light ...

The applicability of optical spectroscopy for intraoperative detection of brain tumors/tumor margins was investigated in a pilot clinical trial consisting of 26 brain tumor patients. The results of this clinical trial suggest that brain tumors and infiltrating tumor margins (ITM) can be effectively separated from normal brain tissues in vivo using combined autofluorescence and diffuse-reflectan...
