Thermography Camera

The VarioCAM® thermography camera from JENOPTIK Laser, Jena, Germany, features an image resolution up to 1.2 megapixels and is designed for applications in scientific and industrial research and development. The camera is based on Resolution-Enhancement-Technology, an optomechanical procedure in which the resolution of the 640 × 480-pixel microbolometer detector is quadrupled during the image saving process. In this way, the camera supplies thermal images with quality almost equal to photographs.

High-Definition Robotic Camera

Sony Electronics, Park Ridge, NJ, has introduced the EVI-HD1 high-definition EVI robotic camera, a single-chip-based, pan/tilt/zoom camera with multi-format capabilities to output both standard and high-definition video. The camera uses a 1080i CMOS sensor that delivers high-definition resolution in 720p, 1080i, or 1080p. The camera can be used with compatible codecs and systems from other manufacturers, due to its ability to output standard-definition video (YC and composite), high-definition analog component (Y, Pub, Pr), or digital HD-SDI.

Adaptive Algorithms, Multi-Cores, and Networks Mark New Machine Vision Era

Potato chips, cell phones, razors, and baby diapers are just a few of the many everyday items made with the help of industrial machine vision. In fact, any product that is manufactured in either high volume, high accuracy, low cost, or a combination of all three can be made better, faster, and less expensively using machine vision.

Infrared Vision: SWIR Sees the Furnace Through the Flames

The ability to make thermal measurements and image through materials that confound more expensive thermal cameras is pushing shortwave infrared (SWIR) sensors into a growing number of industrial process monitoring and thermography applications, typically those of 100 °C or more.

Medical Imaging: Multimodal Techniques Find Life’s Answers

Traditional research on disease mechanisms in animal models mainly has relied either on the detection of morphological changes of the diseased tissues obtained through anatomical imaging, or on the excision and pathological study of the tissues of interest. These methods often require long time periods for measurable changes to occur and large numbers of test animals because multiple animals are often sacrificed at each experimental point for histological testing.

Infrared Cooled Camera

The Silver 480M from Cedip Infrared Systems, Croissy-Beaubourg, France, is an infrared cooled camera that provides an acquisition and processing system for dynamic phenomena and high-frequency periodic excitation. Designed to perform ultra-fast thermographic analysis, the camera uses analog inputs for synchronous acquisition of external sensor signals that, after processing by a lock-in technique, enable non-destructive evaluation, fatigue testing, and stress analysis. The camera is based on the company’s cryogenically cooled staring focal plane array detectors, and incorporates Read Out Integrated Circuit (ROIC) technology. The camera features a 320 x 240 pixel format InSb detector that delivers a 400-Hz full frame rate.
