Hyperspectral imaging, or imaging spectroscopy, is a happy fusion of spectroscopy and imaging processing. It can be seen either as an extension of classical image processing or an enhancement of classical spectroscopy. Hyperspectral Imaging is utilized in a number of different applications ranging from acquiring geological parameters from the air or by satellite, to bio-medical and chemical sample analysis, to industrial process monitoring like vegetation inspection, waste sorting, and moisture measurements. Xenics offers several camera configurations that can be used for spectroscopy. Spectroscopy in the ShortWave InfraRed (SWIR) range proves more and more to be a reliable tool for inline inspection and classification of a variety of products.
Short Wave Infrared for material classification
Because visible cameras can only give us information based on RGB color differences, this can be insufficient when trying to differentiate between objects of similar color using machine vision. Where the visible part of the spectrum only gives us info about the outer layer of the object, SWIR-rays penetrate deeper into the object and provide us with valuable information about the actual molecular structure.
Since each molecule has its own spectral fingerprint, we can thus discern between materials with only the slightest difference in molecular structure just by looking at specific wavelengths.
Applications find their way in food and agriculture, waste sorting, pharmaceuticals, cancer detection… due their ability to identify specific chemical bonds.
High resolution SWIR line-scan cameras
In such cases, high performance InGaAs focal plane and linescan arrays can provide us with the necessary information we need to effectively steer the production process to better yield and efficiency. One of the latest InGaAs line scan cameras, the Lynx 2048, pushes technology to new heights. This camera with a 2048 pixel line array on a 12.5µm pixel pitch will increase the level of detail, and hence delivers more information or resolution to the user. Up till now, these resolution levels could only be obtained using complex multi-camera solutions. Use of the Lynx not only makes these types of setups simpler, but also much cheaper than before.
Xenics covers the full IR spectrum
For all of these techniques, Xenics offers a broad range of infrared cameras with specialty features.
