  • VISION Focus article – Standard CMOS sensors applied to 3D vision, detection, and measurement

    3D imaging technology has been around for several decades, but the first products were only commercialized in the 2000s when major film studios released movies in 3D using the latest HD video cameras.

  • Tech Briefs article – Time-of-Flight: Highly Reliable 3D Imaging for Challenging Applications

    Time-of-flight (ToF) technology enables new applications in multiple markets, resulting in a market boom for time-of-flight CMOS sensors over the last few years. This is mainly driven by the consumer and automotive markets, but also by prosumers — amateurs who purchase equipment with quality or features suitable for professional use.

  • Night-sight: Competing technologies for the vision systems in autonomous vehicles

    At night, the average vehicle high beams can illuminate about 400 feet, far less in inclement weather. And, if you’re traveling at a conservative 55 mph—80 feet per second—that means it will take you about 170 feet to stop once you apply your brakes. But, the average driver will travel 120 feet before the brakes are applied.

  • Behind bars – a technological overview of the most pervasive of coding systems

    Even with the holidays behind us (the seasonal peak in consumer retail/on-line spending, logistics and transport, manufacturing, and distribution), there are still more than 5 billion barcodes are scanned every day. Considering that the first barcode was scanned in the 70s on a packet of chewing gum, it’s clearly a formidable method of providing machine-readable UPC (Universal Product Code) that has evolved relatively little since.

  • A New Dawn for NIR Spectroscopy

    Breakthrough technology in BLAZE® Scientific CCD Cameras greatly enhances near-infrared quantum efficiency and enables superior, quantitative, spectroscopic measurements

  • CCD vs CMOS

    Much has been written about the relative advantages of CMOS versus CCD imagers. It seems that the debate has continued on for as long as most people can remember with no definitive conclusion in sight. It is not surprising that a definitive answer is elusive, since the topic is not static. Technologies and markets evolve, affecting not only what is technically feasible, but also what is commercially viable. Imager applications are varied, with different and changing requirements. Some applications are best served by CMOS imagers, some by CCDs. In this article, we will attempt to add some clarity to the discussion by examining the different situations, explaining some of the lesser known technical trade- offs, and introducing cost considerations into the picture.

  • Color Line Scan Imaging

    Teledyne DALSA offers a range of color line scan cameras to serve applications from the most price-conscious to the most performance-hungry. From clever bilinear to benchmark trilinear to innovative quadlinear products that extend into the multispectral range, our latest CMOS line scan cameras give you the power and performance to conquer color imaging applications such as recycling, postal and parcel sorting, transportation, food and web inspection.

  • Spectral Imaging of Plasmonic Nano-Structures

    Prof. Adi Salomon’s lab is primarily interested in understanding the interactions of molecules with light at the nanoscale and build devices for sensing molecules using light

  • Electrophysiology and FRET

    Calcium ion (Ca2+) is a second messenger involved in various physiological phenomena. In contrast to the high Ca2+ concentration (2 mM) in the extracellular fluid, cells maintain the cytosolic Ca2+at nM concentration.

  • Spinning Disk Confocal In Vivo Imaging

    The Johns Hopkins University School of Medicine Microscope Facility has an expansive selection of research microscopes, including multiple laser scanning confocal microscopes, a multiphoton microscope, an atomic force microscope, a TIRF microscope and multiple spinning disk confocal microscopes.

  • Super Resolution Microscopy (SptPALM/STORM)

    Research at the Nanoorganization Lab, Centre for Neuroscience, Indian Institute of Science in Bangalore India borders on the interface of single molecule spectroscopy and molecular and cellular neuroscience. Here, team members develop and adapt state of the art paradigms in ultra-high and super resolution microscopy to image molecules at the synapses of living neurons.

  • Single Molecule Spectroscopy at Sussex University

    Research at Sussex University focuses on the development and application of ultrasensitive optical techniques for the detection and manipulation of single molecules. Representing the ultimate level of sensitivity in the analysis and control of matter, single molecule techniques have many advantages over conventional ensemble methods, namely the measurement of static and dynamic heterogeneity in molecular systems.
