Purposes For Hyperspectral Imaging

The human eye is limited in the kinds of light and images that it can see. Some types of light or spectra can be seen, like red, blue and green. These are known as the visible spectra. However, there is light that human eyes aren't able to observe on their own. Infrared spectra and ultraviolet light constitute two of these types of light that can't be seen with the human eye alone. There are a number of devices that aid the human eye in seeing spectra that are normally invisible. What if there was a way to observe things that looked the same, or were spectrally similar, and distinguish between them? This is precisely what hyperspectral imaging will do. This type of imaging helps to facilitate very accurate and detailed info. Hyperspectral imagers allow for remarkably detailed data because of the fact that they have the capability to view many light wavelengths and the measurements are narrow and continuous. There are a number of applications for hyerspectral imaging in a range of fields. It can be used in the food and agriculture industry to examine food that is produced, but also to examine soil samples and different blends. One of the advantages of this kind of imaging is that it can be done as part of the production line so that analysis doesn't have to delay production. It also does not create any heat that will damage sensitive produce. A similar process can be used in the production of pharmaceuticals. The distribution of chemicals in drugs can be essential to its effectiveness. Hyperspectral imaging makes it possible for drug manufacturers to get a firm handle on their quality control because it doesn't damage the products. Mining is another industry that has application for this sort of spectral imaging, because it can be used by geologists to tell apart minerals in the soil or rock that can be extracted. Not only that, it can detect toxic substances and heavy metals that can be waste products of mining. The imaging can be utilized throughout a mining site that is active and even a site that has been fully mined and simply needs to be cleaned up. Hyperspectral imaging can additionally be utilized in the forensics industry within both criminal investigations and civil lawsuits. It has been confirmed to be effective in detecting and even identifying explosive chemicals in fingerprints. It can also identify minute variations that cannot be seen with the naked eye with regards to document forgery. Detecting and analyzing patterns created by blood spatter at crime scenes is also something that can be enhanced with this kind of imaging. There are a variety of manufactured products, such as semiconductors, mirrors, and devices with photovoltaic lenses which need thin films. Sometimes particular qualities of these films are important to the final product created. Manufacturers need to know the thickness of the films and perhaps the reflectivity or the refractive index as well. This data can be furnished through the help of assessing hyperspectral images. Yet another significant use of hyperspectral images is the analysis of works of art. It's made use of by experts to detect forgeries and to assess what an original paint color was before it faded due to elements like light or the passage of time. This can be useful in restoration work. The field of hyperspectral imaging continues to increase as new applications for this sensitive imaging are identified.
