  1. High-Speed Imaging Techniques For The Aerospace Industry
    8/15/2019

    For many years high-speed imaging has been used in various applications by engineers in the aerospace industry. Three very common imaging techniques utilized by these engineers are Digital Image Correlation, Particle Image Velocimetry, and Schlieren Imaging. These imaging techniques provide engineers with great insight into various aspects of the strength and durability of materials, the characteristics of engine combustion processes, the aerodynamics of objects in flight, and much more.

    A new generation of advanced UV imaging cameras has opened the door to new applications and enhanced performance in existing applications.

  4. Detecting Disguises At Border And Immigration Security Checkpoints Using Short Wave Infrared (SWIR) Cameras
    8/8/2019

    As the US continues to increase its security at border crossings, airports and other points of entry, biometrics will play an important role. Fingerprints and other direct contact means will become final identifiers of persons.

  5. Controlling Hexapod 6-DOF Alignment Robots Via EtherCAT®
    8/7/2019

    This white paper presents the latest generation of PI hexapod controllers with integrated EtherCAT interface now make it very easy for users to integrate hexapods into automation systems without the need for to perform challenging kinematic transformations.

  6. ISO Compliance Of Non-Contact, Real-Time Beam Analysis
    8/1/2019

    To deliver continuously high product quality, the key parameters of laser beams in production applications must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology, the BeamWatch, based on the Rayleigh scattering. As this technology is relatively new, it has not made its way into the ISO standard, but it is still of high importance for users of fiber laser technology to trust on the accuracy and repeatability of their measurements. This white paper we will provide a comparison between Rayleigh Scatter based beam profiling methods and other beam profiling techniques used to measure beam propagation parameters.

  7. Battle Axe vs. Scalpel: How To Work With High Power Density Lasers
    8/1/2019

    There will always be opportunities for improvement in lasers. In this Q&A article, Mark Gitin, Senior Vice President and General Manager of the Light & Motion Division of MKS Instruments, and Christian Dini, Director Global Business Development, Ophir, discuss the use of reliable laser beam measurement technology that can help with the process of laser optimization.

  8. Strategic Prototyping For Human-Factors Engineering
    7/26/2019

    Human-Factors Engineering (HFE) is gaining increasing attention, especially in the context of medical device product development. As technologies evolve, therapies advance, and devices become more complex, so does the role of HFE increase in priority.

  9. Keeping You Safe In The ‘Pool’ Of Manufacturing
    7/26/2019

    Protolabs provides medical device and medtech companies with a dramatically reduced level of risk. Working with us directly, you know the ability of everyone in our “pool,” so you don’t have to white-knuckle it, wondering where and how your parts are being produced. 

  10. Shortwave Infrared Cameras For High-Temperature Manufacturing And R&D Processes
    7/25/2019

    Shortwave infrared (SWIR) cameras are sensitive to shorter IR wavelengths between visible light and 3 µm. They've historically been used for qualitative imaging applications like laser beam profiling, silicon wafer inspection, and imaging through layers of paint/ink and not for actual quantitative temperature measurement applications. Now, with the addition of temperature measurement capabilities, SWIR cameras offer a win-win for anyone concerned with thermal analysis of high temperature materials or processes.
