Dr. Gerhard Holst, PCO AGBiologists use high-speed imaging to study how microorganisms move. Some like it hot – for example, micro-organisms that live in the deep sea on “black smokers,” where heat rises from the interior of the earth. These archaea, or “ur-bacteria,” form a separate branch in the phylogenetic tree of life and are veritable survival artists: They become active only at temperatures of 75 °C or higher, and thrive at temperatures between 80 and 100 °C. To find the temperate zone between the 400 °C water coming from inside the earth and the cold sea water...Read full articleRelated content from Photonics MediaARTICLESImager Could Help Autonomous Vehicles See Around CornersAn around-the-corner camera system built by engineers at Stanford University uses a wave-based image formation model to allow non-line-of-sight (NLOS) imaging.

Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookIndustrial Lasers: An Introduction to Process Qualification: The step from successfully demonstrating a new laser process on a limited number of samples under laboratory conditions, to scaling that process up for high-volume industrial use is a big one. In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1.
