Light field microscopy methods together with three-dimensional (3D) deconvolution can be used to obtain single-shot 3D images of atomic clouds. We demonstrate the method using a test setup that extracts 3D images from a fluorescent Rb87 atomic vapor.

Zusammenfassung Im Vergleich zu den traditionellen Clusteringverfahren ermöglicht Subspace Clustering die Suche nach Clustern in den Unterräumen (Subspaces) der Daten. Man unterscheidet zwei Hauptarten des Subspace-Clustering-Verfahrens: Top-Downund Bottom-Up-Verfahren. Die Algorithmen des Top-Down-Verfahrens verkleinern die Suchbereiche von hohen zu niedrigen Dimensionen. In dem Bottom-Up-Verf...

We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference wave created by four-wave mixing in the nonlinear medium can interfere with the CARS signal generated in the specimen to result in an inline hologram. We experimentally and theor...

The introduction of affordable, consumer-oriented 3-D printers is a milestone in the current "maker movement," which has been heralded as the next industrial revolution. Combined with free and open sharing of detailed design blueprints and accessible development tools, rapid prototypes of complex products can now be assembled in one's own garage--a game-changer reminiscent of the early days of ...

We show that three-dimensional incoherent primary sources can be reconstructed from finite-aperture Fresnel-zone mutual intensity measurements by means of coordinate and Fourier transformation. The spatial bandpass and impulse response for three-dimensional imaging that result from use of this approach are derived. The transverse and longitudinal resolutions are evaluated as functions of apertu...
