Introduction To Fiber Laser Marking

While laser marking systems employ exactly the same principle as burning leaves with a magnifying glass, the process is slightly more complicated. Instead of sunlight being passed through a simple lens, laser light is passed through a more complex lens — an f theta lens. And, while sunlight consists of many colors or wavelengths, laser light has the property of being monochromatic. This article provides an introduction to fiber laser marking and explains the three most important settings that can affect how a part is marked.

    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.

TECHNICAL ARTICLES

  • Rolling Shutter Vs. Global Shutter

    Two image sensor types widely used in cameras for microscopy are scientific grade Charge Coupled Devices (CCD) and scientific Complementary Metal Oxide Semiconductors (CMOS or sCMOS). There is a number of similarities between the two technologies, but one major distinction is the way each sensor reads the signal accumulated at a given pixel. This technical article explains how the differences in readout modes impact the exposure timing, illumination, and triggering of cameras and light sources in microscopy experiments.

  • Camera Requirements For 3D Metrology

    As the objects to inspect/measure in high-tech manufacturing become smaller, higher-resolution cameras with better spatial resolution can improve accuracy and precision. This does require a high-quality machine vision camera design, however, or what is now called a metrology camera. 3D measurements in particular pose increasing demands on camera performance and reliability. This article discusses critical parameters, depending on the specific measurement.

  • Innovation In CMOS Bio-Optical Sensors Enables Portable Diagnostics

    In the past 10+ years we have seen great progress in molecular diagnostic technologies. Doctors can now take advantage of the emerging nucleic acid or protein analysis techniques to get very precise answers about the type of virus, bacteria, or cancerous cells that cause illnesses. This article provides an in-depth look at a new CMOS image sensor design that enabled the development of a low-cost, portable molecular diagnostic system. By Zhimin Ding, Anitoa Systems, LLC
