  1. The Eyes Of The Instruments: Using Optical Filters To Observe And Measure Earth From A Different Perspective

    An improved ability to manage or understand the natural or influenced phenomena is critical to ensuring that we maintain a healthy planet capable of sustaining humanity as part of its diverse biomass. But understanding these phenomena and how they are changing over time requires measurement.

  2. When Custom Costs Less Than Standard: The Benefits And Flexibility Of Custom Optical Assemblies

    Here are a few questions you might be asking when you’re considering whether to build your own assembly or have it custom-made by an experienced design and manufacturing team.

  3. Precision Explosives Analysis Using High-Speed Imaging

    High-speed imaging can be used to quantitatively capture explosions, the resulting damage, and to measure other important parameters of the explosion. The data collected can aid in the understanding and characterization of a detonation.

  4. Frictionless Precision Motion Control Based On Air Bearing Stages - Key Element In Coordinate Measuring And Surface Metrology Applications

    The performance of precision metrology equipment depends on highly accurate, repeatable, and controllable motion systems and position sensors. Air bearings have played a critical role in the development and construction of CMMs and other metrology tools. 

  5. Automotive Precision Assembly: Hexapod 6-Axis Parallel Machines Add High Precision To Conventional Robots

    The need for advances robotics with high precision and alignment requirements continues to grow in the automotive industry. This white paper describes the major benefits that hexapod 6-axis parallel machines have for conventional robots in automotive precision assembly lines. 

  6. Engineered Precision Motion Design Benefits From Systems Approach

    When controlling motion at the sub-micrometer or nanometer levels for alignment and handling applications, it is imperative to have high reliability, robustness, minimized latency, and high-speed synchronization with external devices to reach sub-micrometer path accuracy. The higher the dynamics and throughput targets of a multi-axis precision motion system, the more holistic the design approach must be in order to achieve success. A systems approach where the mechanics, control electronics, and software are designed by the same team provides a great amount of benefits for the user.

  7. When Lightning And Rods Connect

    Marcelo Saba is a modern-day Doc Brown–except that instead of capturing lightning to power a DeLorean time machine in Back to the Future, Saba captures lightning with high-speed cameras to not only advance the understanding of how lightning connects with lightning rods, but also provide the field data necessary to improve current lightning protection systems.

  8. The Instrument Transfer Function

    An Interferometer's ability to quantify mid-spatial frequency content is defined by its sampling density and design aspects of the optical illumination and imaging system. The instrument transfer function (ITF) quantitatively characterizes the response of the instrument as a function of spatial frequency.

  9. Selecting A Hyperspectral Imager To Bring Critical Data Into View

    The hyperspectral imager comes with challenges, not the least of which is choosing the right one to use for any given application. That decision depends in part on the user’s requirements, the wavelength range in which the imager will be used, and the intended application.

  10. Fiber Optic Sensing

    The two types of sensing include local measurement points and distributed sensing. This paper presents the technical basics behind sensing over fiber technologies, its main applications, and the cabling solutions involved.
