  1. Analyzing Small, High Power Beams At Focus In Manufacturing Applications
    2/14/2019

    Lasers are increasingly deployed in manufacturing applications, being pushed to higher output powers and smaller beam sizes to work faster and with higher precision. Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. 

  2. Optical Micromirrors Reveal The Secrets Of Cell Membranes
    2/13/2019

    Progress in understanding the lipid bilayer – a two-molecule thick oily barrier that protects all living cells – has been dramatic over the past 100 years. But puzzles remain to be solved, such as how these membrane proteins navigate the oily lipid bilayer to go about their work. 

  3. Poking And Prodding The Molecules Of Life
    2/13/2019

    Applying physics to the properties and underlying structures of the molecules of life offers an insight into the mechanisms that make living beings tick. But even seemingly simple actions like muscle contraction involve a wide array of biological interactions. 

  4. Specifying Surface Figure And Wavefront Distortion For Multi-layer Optical Filters
    1/15/2019

    Optical filters are used in many applications and the surface figure and wavefront distortion requirements of filters are dependent on where and how they are used. If filters are only used in sensing applications with very tolerant detector geometries, there may be no need, in practice, to put any constraints on the surface figure or wavefront distortion. This white paper helps the reader understand where, when, how, and how much to specify wavefront distortion to ensure that functional requirements of filters are guaranteed while unnecessary and costly constraints are avoided.

  5. Making Waves: Nanosecond Pulsed Drivers For Flash LiDAR
    1/7/2019

     The limiting factor on a diode laser’s pulse features is not the laser itself — it is the electrical driver that supplies the electrons to the laser diode. This paper discusses challenges involved in optimizing nanosecond electrical driver performance in a flash LiDAR system.

  6. The HOT Infrared Imaging Market is Heating Up
    12/20/2018

    New infrared camera cores with high operating temperatures allow the construction of imaging systems that are smaller, lighter, and less power-hungry. That’s opening up new uses, from airborne to hand-carried applications.

    12/11/2018

    Sony's Pregius global shutter CMOS technology truly fulfills its promise: crisp, clear, distortion-free images at high speeds. regius offers significant performance gains, and with its newly-announced third generation, additional on-sensor features.

  9. Imaging Reflective Surfaces: Getting Started with On-sensor Polarization
    12/11/2018

    Many vision systems struggle to overcome the effects of reflections and glare on reflective surfaces like glass, plastic and metal. Sony’s newest sensor technology can solve this problem with its pixel-level polarizer structure. This technology enables Sony polarized sensors to detect both the amount and angle of polarized light across a scene.
