We study the feasibility of a new generation axion helioscope, most ambitious and promising detector solar axions to date. show that large improvements in magnetic field volume, x-ray focusing optics backgrounds are possible beyond those achieved CERN Axion Solar Telescope (CAST). For hadronic models, sensitivity axion-photon coupling gaγ ≳ few × 10−12 GeV−1 is conceivable, 1–1.5 orders magnitude CAST sensitivity. If also couple electrons, Sun produces larger flux for same value Peccei-Quinn...

In computational imaging by pattern projection, a sequence of microstructured light patterns codified onto programmable spatial modulator is used to sample an object. The are as generalized measurement modes where the object information expressed. this Letter, we show that resolution recovered image only limited numerical aperture projecting optics regardless quality collection optics. We provide proof-of-principle experiments single-pixel detection strategy outperforms achieved using...
Precise control of light propagation through highly scattering media is a much desired goal with major technological implications. Since interaction turbid results in partial or complete depletion ballistic photons, it principle impossible to transmit images distances longer than the extinction length. In biomedical optics, dominant process accounting almost exclusively for limited imaging depth range. addition, most interest are dynamic sense that scatter centers continuously change their...
Sodium Iodide scintillators are very interesting particle and radiation detectors. Low background requirements could limit their application in a variety of fields. We report the e.orts to understand reduce set 14 NaI detectors, stored underground since 1988, undertaken frame ANAIS experiment [1] several directions, including PSD techniques, Monte Carlo simulations detector upgrading.
The Scanning Electron Microscopy (SEM) and Optical (OM) with integrated digital camera are techniques that used in the present investigation, for morphological characterization of a new composite material called “organic polymer concrete” which microparticles added fibers polyethylene terephthalate (PET) recycling mechanically (RM). Polymer concrete (PC) is (MC) application considered as an alternative construction reinforcement particles recycled polymers have approximately same dimensions...
Despite imaging systems that scan a single-element benefit from mature technology, they suffer acquisition times linearly proportional to the spatial resolution. A promising option is use single-pixel system benefits data collection strategies based on compressive sampling. Single-pixel also offer possibility dedicated sensors such as fiber spectrometer for multispectral or distribution of photodiodes 3D imaging. The image obtained by lighting scene with microstructured masks implemented...

Raster scanning is a method which can be useful in different kinds of imaging techniques. Using simulations, we show that Fourier ptychography algorithm improve raster resolution, even using objectives with low NA.
In this work we have developed a single-pixel optical microscope that provides both reflection and transmission images of the sample under test by attaching diamond pixel layout DMD to commercial inverted microscope. Our system performs simultaneous measurements modes. Besides, in contrast with conventional system, our single-element detection belong, unequivocally, same plane sample. Furthermore, designed an algorithm modify shape projected patterns improves resolution prevents artifacts...

Single-pixel detection approaches have been applied with success in different imaging techniques such as optical microscopy. Here we show that it is possible to improve the resolution of single-pixel microscopy by using an array of photodetectors and Fourier ptychography algorithms.
