The Advantages Of Piezo-Based Scanning Systems For High-Performance Microscopes

Classical microscopic methods are no longer sufficient in terms of optical resolution or information content. To obtain more extensive and accurate measurement data of a sample, it is now possible to combine different microscopic methods. Combining those methods, however, is very demanding on the positioning system. This article outlines the advantages of using piezo-based scanning stages to ensure image position resolution and accuracy.

    Hybrid Materials Could Smash The Solar Efficiency Ceiling

    Researchers have developed a new method for harvesting the energy carried by particles known as ‘dark’ spin-triplet excitons with close to 100% efficiency, clearing the way for hybrid solar cells which could far surpass current efficiency limits.

    Revving Up Fluorescence For Superfast LEDs

    DURHAM, N.C. - Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal - setting a speed record and making an important step toward realizing superfast light emitting diodes (LEDs) and quantum cryptography.

  • Getting Sharp Images From Dull Detectors
    Getting Sharp Images From Dull Detectors

    Observing the quantum behavior of light is a big part of Alan Migdall’s research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons---the particle complement of light waves---and sometimes only one photon at a time, using “smart” detectors that can count the number of individual photons in a pulse.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

  • Miniature Camera Modules For Visualizing Micro Invasive Surgery

    The miniaturization of camera modules allows visualization inside the body with ever smaller incisions. These miniature digital camera modules — hardly bigger than a grain of salt — enable novel medical tools, where visualization is possible for the first time and where previous procedures had to be done completely blind. In this article, AWAIBA, a reputed leader in miniature camera modules as small as 500 mm side length, provides an overview of these miniaturized cameras and explores potential new applications for the technology.

  • Cherenkov Emission Imaging And Spectroscopy Utilizing Isotopes And A Linear Accelerator

    There are linear accelerators (LINACs) employed in radiation oncology that produce radiation in pulsed microseconds-long bursts, generated by the accelerator waveguide. By taking advantage of a LINAC’s inherent pulsed operation, time-gated detection of Cherenkov radiation is possible, significantly improving the ratio of signal to ambient light. Recently, a research group at Dartmouth College and Dartmouth-Hitchcock Medical Center in New Hampshire led by Dr. Brian Pogue has investigated fluorescence and absorption spectroscopy methods using pulsed LINAC-induced CES2, under ambient room lighting conditions. An overview of some of their work is provided in this application note.

  • How To Assess Thermal Camera Range For Site Design

    When laying out a site design for surveillance using currently marketed uncooled thermal cameras, it is important to understand the coverage capability of the cameras under evaluation in terms of field of view and range. Accurately gauging range performance from the onset of the site design may allow one to avoid unintended and pricey rework costs later. The following white paper explores the various determinants that are needed for thermal camera range capability assessment.

  • How To Push Conventional 2-Sided Contacted Solar Cells To The Max

    Of the silicon solar cells commonly manufactured today, 90 percent are based on screen-printed Ag front contacts and an aluminum-BSF (Back Surface Field) as rear passivation. Their success lies in the relatively low manufacturing cost and straightforward production technology. But they also have a downside: the typical efficiency on monocrystalline silicon is limited to about 19 percent. To overcome this hurdle, alternative cell concepts are being developed, such as PERx-type solar cells, promising efficiencies of 22 percent and higher. Researchers at imec have developed n-PERT solar cells, a specific version of a PERx-type cell with unique properties, achieving as much as 21.5 percent with a clear roadmap to reach 22.5 percent.
