State of the Art and Prospects for Halide Perovskite Nanocrystals
(American Chemical Society, 2021-06-17)
Metal-halide perovskites have rapidly emerged as one of the most promising materials of the 21st century, with many exciting properties and great potential for a broad range of applications, from photovoltaics to optoelectronics ...
Use of polar decomposition of Mueller matrices for optimizing the phase response of a liquid-crystal- on-silicon display
(Optical Society of America, 2008)
We provide experimental measurement of the Mueller matrices
corresponding to an on-state liquid-crystal-on-silicon display as a function
of the addressed voltage. The polar decomposition of the Mueller matrices
determines ...
High sampling rate single-pixel digital holography system employing a DMD and phase-encoded patterns
(Optical Society of America, 2018)
A single-pixel digital holography system with phase-encoded illumination using a
digital micromirror device (DMD) as a spatial light modulator (SLM) is presented. The
enhanced switching rate of DMDs, far exceeding the ...
Optical filters with fractal transmission spectra based on diffractive optics
(Optical Society of America, 2009)
The duality between the axial irradiance distribution originated by any circularly symmetric diffracting aperture under monochromatic illumination and its diffracted spectral intensity at a fixed on-axis point under broadband ...
Tunable telephoto: governable Fourier spectrum anamorphic scaling
(2021-02-18)
We discuss the Gaussian design of a device that controls the scale, in an anamorphic fashion, of Fraunhofer diffraction patterns. The device uses two pairs of varifocal cylindrical lenses. For spherical lenses, the optical ...
Optical Filter Based on a Spatially Patterned Kinoform Diffractive Lens
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
We demonstrate a compact all-diffractive setup for spectral synthesis. The system is composed of a circularly symmetric mask attached to a kinoform diffractive lens. Following diffraction-based analysis, a Fourier transform ...
Phase calibration of spatial light modulators by means of Fresnel images
(Institute of Physics, 2009)
Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements
requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the
evaluation of ...
Fast compressive Raman bio-imaging via matrix completion
(Optical Society of America, 2019)
Raman microscopy is a powerful method combining non-invasiveness with no special sample preparation. Because of
this remarkable simplicity, it has been widely exploited in many fields, ranging from life and materials ...
Harnessing prion-inspired amyloid self-assembly for sustainable and biocompatible proton conductivity
(Royal Society of Chemistry, 2024-04)
Protein-based materials have emerged as promising candidates for proton-conducting biomaterials. Therefore, drawing inspiration from the amino acid composition of prion-like domains, we designed short self-assembling ...
Single-pixel imaging through non-homogeneous turbid media with adaptive illumination
(Optica Publishing Group, 2024-03-29)
The presence of scattering media limits the quality of images obtained by optical systems. Single-pixel imaging techniques based on structured illumination are highly tolerant to the presence of scattering between the ...
