  1. Understanding Fluorescence Imaging

    Many modern biological and biomedical research applications rely in part on fluorescence imaging to understand cellular structures and events. This application note details the techniques involved in fluorescence imaging, as well as possible imaging considerations, providing a point of reference for quantitating data obtained from images or movies.

  2. Guide To Glass

    Abrisa Technologies’ "Guide to Glass" provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties. This download also helps the reader better understand light and color; glare reduction; and glass strengthening methods using heat and chemicals.

  3. What Are All The Discussions About Global Vs. Rolling Shutter?

    The shutter in a camera system enables the control of the exposure time and thus, the level of signal in an image. The shutter also defines the quality of an image if the objects are moving, as well as setting the environment for experiments, especially involving synchronization with illumination light.

  4. A LiDAR Designer’s Guide To Sensor Technologies For Automotive/Mobility Systems

    How design engineers for original equipment manufacturers (OEMs) of LiDAR systems can choose between differing sensor technologies.

  5. New High-Speed Lighting Technique Illuminates ‘Ride Of The Valkyries’ In Marvel Blockbuster

    Using a Phantom camera and custom lighting rig, one creative studio found a way to move light at eight times the speed of sound – a new lighting technique for high-speed imaging that gained critical acclaim in Thor: Ragnarok.

  6. Phantom High-Speed Camera Goes Where No Welding Camera Has Gone Before

    One Brazil-based R&D company is using high-speed imaging to observe and improve arc welding processes—a field of research that has vast implications for oil companies.

  7. A High-Speed Look At Downhole Oil Well Cleaning

    With the ability to record up to 1,000,000 fps, Vision Research’s Phantom v2511 high-speed camera helped Olson Technologies see how their Plasma Blaster unclogs underground oil wells.

  8. How To Interpret Images From Infrared Cameras

    Real-life interpretations of infrared images from a variety of field applications may become complex. In order to make the most accurate interpretation, the camera user must know about the measurement conditions as well as have a good foundation in radiometry. This white paper will discuss how to establish a simple scene model in the field, how to determine their limitations, and how you can use these models to estimate physical parameters, such as the thermodynamic temperature of the objects being viewed.

  9. Radiometry 101

    Radiometry is the science of studying the transport of energy through radiation. In this article, Telops presents the basics of the principal laws of radiometry as seen through light-sensitive instruments.

  10. Optics For Lasers Of The Future

    Many research centers, like those for nuclear fusion and cancer, require high-energy lasers with megawatt and petawatt power capabilities. For centers like these to make breakthroughs, the optics used must be extremely robust with low absorption levels and state-of-the-art coating.
