Visible spectrum extended-focus optical coherence microscopy for label-free sub-cellular tomography. [PDF]
Biomed Opt Express, 2017 We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 {\mu}m axial and 0.4 {\mu}m lateral resolution maintained over a depth of 40 {\mu}m, while preserving the advantages of Fourier domain OCM.

Biometric presentation attack detection: beyond the visible spectrum [PDF]
, 2019 The increased need for unattended authentication in multiple scenarios has motivated a wide deployment of biometric systems in the last few years. This has in turn led to the disclosure of security concerns specifically related to biometric systems ...

Surface-enhanced Raman spectroscopy of DNA bases [PDF]
, 1986 A Raman microprobe has been used to measure the surface-enhanced Raman spectra of adenine, guanine, cytosine and thymine. Comparison of the SERS spectrum with solution spectra shows that some line positions are not influenced by the adsorption process ...

Deep Perceptual Mapping for Thermal to Visible Face Recognition [PDF]
, 2015 Cross modal face matching between the thermal and visible spectrum is a much de- sired capability for night-time surveillance and security applications. Due to a very large modality gap, thermal-to-visible face recognition is one of the most challenging ...

Fourier transform infrared spectrometer for a single aerosol particle [PDF]
, 1987 A spectrometer is reported here for obtaining the infrared spectrum of a single aqueous aerosol particle by a Fourier transform technique. The particle is held in an electrodynamic balance and irradiated simultaneously by the infrared output from a ...

Dual-band, double-negative, polarization-independent metamaterial for the visible spectrum
, 2012 We present the first dual-band negative index metamaterial that operates in the visible spectrum. The optimized four-functional-layer metamaterial structure exhibits the first double-negative (i.e., simultaneously negative permittivity and permeability ...

Stable Monolayer alpha-Phase of CdTe: Strain-Dependent Properties [PDF]
, 2017 CdTe is a well known and widely used binary compound for optoelectronic applications. In this study, we propose the thinnest, free standing monolayer of CdTe which holds the tetragonal-PbO (alpha-PbO) symmetry. The structural, electronic, vibrational and
