Most engineers are familiar with charge-coupled devices (CCDs) employed as image sensors. Pixels in a CCD sensor consist of P-doped metal-oxide semiconductor capacitors arranged in columns and rows to form an array. Light striking each pixel is converted to an electrical charge that varies according to the light intensity at that pixel. The CCD transfers […]

New thermal imaging software for Research and Development (R&D) and science professionals is available for a free trial download. FLIR Research Studio is designed for use across multiple platforms and in 22 languages, to allow R&D and engineering teams to collaborate on thermal data collection, analysis, and sharing. In combination with a FLIR thermal imaging […]
Test instruments that aid PCB repair tasks
Basic tools such as DMMs and oscilloscopes may be the only test gear needed for small printed circuit board repairs, but it pays to know when automated systems would be a better choice. Alan Lowne | Saelig Co. Inc. PCBs are more complicated to repair today than even a few years ago. Manufacturing mistakes and […]
Thermal analysis software works with FLIR thermal imaging cameras
The FLIR Research Studio is new thermal imaging software for Research and Development (R&D) and science professionals. Available for a free trial download starting today, FLIR Research Studio is designed for use across multiple platforms and in 22 languages, to allow R&D and engineering teams to collaborate on thermal data collection, analysis, and sharing. In […]
The difference between spontaneous emissions and stimulated emissions
The terms spontaneous emission and stimulated emission sometimes get confused. The term thermal emission sometimes gets thrown into the mix as well. Here are the basic definitions to help sort things out and the procedures for measuring these parameters. When we speak of spontaneous or stimulated emissions we are referring to atoms whose electrons are […]
Infrared cameras for PCB development and diagnosis
Infrared cameras can help size up the surface temperatures of electronic components, PCBs, and other objects to reveal unseen problems. ALAN J. LOWNE, SAELIG CO. INC. Thermal imagers, also called infrared cameras, capture a 2-D representation of objects in front of their germanium optics (ordinary optical glass impedes IR wavelengths). They present a visible version […]
Infrared cameras include Matlab, LabVIEW plug-ins
New Fluke RSE300 and RSE600 Infrared Cameras are said to be the first fully-radiometric, fixed-mount cameras from Fluke with advanced features including Matlab and LabVIEW software plug-ins to easily analyze thermal data. The RSE300 and RSE600 cameras continuously stream up-to-60 frames of data per second, allowing for detailed monitoring of temperature patterns and variances. With […]
Cloud-based professional thermal cameras handle pre-fire detection
The Fotric 123 Infrared Thermal Camera is the world’s first cloud-based smart infrared camera designed for visual early fire detection that offers real-time data transmission. The Fotric 123 can be permanently situated indoors or outdoors to detect abnormal changes in heat conditions and send early fire alert warnings via an internet connection before a fire […]
