  1. Thermal Imaging Helps To Study Non-Contact Electromagnetic Induction Heating For Eradicating Bacteria And Yeasts From Metal Implants

    Infections in joint replacement surgery are a major factor in the failure of the used metal implants, especially when more strains of bacteria become resistant to antibiotics. Heating up the joints would eliminate bacteria and yeast, but the concern is whether or not this can be done in a non-invasive fashion.

  2. LIST Researchers Use FLIR Cameras To Study The Electrocaloric Effect

    Refrigerant devices typically use fluid coolants turned into gases to cool things down. These gases, however, may become harmful to the environment, so research is being done on the use of solid materials as a substitute to cool down food, beverages, medicine, and even electronic devices. Researchers at the Luxembourg Institute of Science and Technology (LIST) are making use of FLIR’s thermal imaging cameras to study the subject.

  3. Development Of A 3D Thermal Image Camera System To Perform Analyses From The Air

    In response to the need for recording 3D thermal images, a team at a university in Germany developed a thermal imaging/RGB system capable of delivering 3D imagery by overlapping pictures from four digital and four FLIR A65sc cameras with 25° fields of view.

  4. Use Low-Cost Materials To Increase Target Emissivity

    Clean, unoxidized, bare metal surfaces have such low emissivity that they are difficult to measure with a thermal imaging camera. In order to get good measurements, the emissivity of these surfaces needs to be increased. This application note describes how to use a variety of low-cost materials to increase target emissivity in many industrial R&D and electrical applications.

  5. “Dynamic” Deadfront Interface Panel Glass

    A “dynamic” deadfront panel is used to create a sleek, uncluttered user interface appearance, drawing attention to the “hidden” light up indicators as required. The icons or other alpha-numeric indicators are visible when backlit, and when unlit, a monochromatic streamlined look is achieved. Abrisa Technologies offers complete solutions for deadfront panel glass technologies including screen printed graphics, chemical strengthening or heat tempering, anti-scratch coatings, and more.

  6. Thermal Lock-In Inspection Of Semiconductor Devices

    Thermal imaging cameras can be utilized as powerful tools for semiconductor failure analysis. This application note discusses the value and effectiveness of using thermal lock-in when conducting semiconductor inspections.

  7. How To Specify A Filter

    In general, typical filter optical specifications will include the wavelength ranges over which to reflect and transmit light, angle of incidence tuning range, clear aperture of the filter, the polarization state of light for non-normal angles of incidence, light coherency (laser or white light), optical beam size and cone angle of light, desired substrate material (with dimensions), incident light medium (air or glass) and so forth. 

  8. Drones Will Change The World

    For autonomous flight, UAVs must independently detect obstacles and avoid them, monitoring their surroundings with LiDAR systems. This white paper discusses how the future of drones and UAV technologies will change the world we live in.

  9. Highest Quality Laser Interferometer Measurements Require Highest Quality Reference Optics

    Fizeau interferometers are used to measure the shape and quality of optical surfaces with high precision by comparing the optic under test to a reference optic. However, it is important to remember that not all reference optics are created equal, as design and construction may cause quality fluctuation. 

  10. Machine Vision Tools Enhances 2D And 3D Surface Metrology And Inspection

    In metrology and process control, vision software must be able to identify all dimensions presented and have the ability to auto adjust the alignment accordingly. ZYGO recognized that and sought to make the process simpler for all involved.
