Printable Nanoscopic Metamaterial Absorbers and Images with Diffraction-Limited Resolution.
The fabrication of functional metamaterials with extreme feature resolution finds a host of applications such as the broad area of surface/light interaction. Nonplanar features of such structures can significantly enhance their performance and tunability, but their facile generation remains a challenge. Here, we show that carefully designed out-of-plane nanopillars made of metal-dielectric comp...
متن کاملThe theory of diffraction-limited resolution in microparticle image velocimetry
A theory of diffraction-limited spot size is developed for infinity-corrected microscope optics. Previously reported formulae were originally derived using a single-lens system. In addition, the previously reported relationship between f -number and numerical aperture assumed a paraxial approximation and was limited to air-immersion lenses. Here, a new relationship between f -number and numeric...
متن کاملPhotoactivatable fluorescent proteins for diffraction-limited and super-resolution imaging.
Photoactivatable fluorescent proteins (PA-FPs) are molecules that switch to a new fluorescent state in response to activation to generate a high level of contrast. Over the past eight years, several types of PA-FPs have been developed. The PA-FPs fluoresce green or red, or convert from green to red in response to activating light. Others reversibly switch between 'off' and 'on' in response to l...
متن کاملdiffraction-limited storage rings
This article summarizes the contributions in this special issue on DiffractionLimited Storage Rings. It analyses the progress in accelerator technology enabling a significant increase in brightness and coherent fraction of the X-ray light provided by storage rings. With MAX IV and Sirius there are two facilities under construction that already exploit these advantages. Several other projects ar...
متن کاملSub-diffraction resolution pump-probe microscopy with shot-noise limited sensitivity using laser diodes.
We demonstrate the use of intensity-modulated laser diodes to implement pump-probe microscopy and achieved sub-diffraction resolution imaging with shot-noise limited sensitivity with a scheme of balanced detection. This technique has several applications for various types of induced transmission change, including excited-state absorption, ground state absorption bleaching and stimulated emissio...
