The Breakthroughs Of Hyperspectral Imaging Systems

By Patricia Parker

Human vision is severely limited in that it can only detect three primary colors in the spectrum of visible light. Really, this places us in the lower echelons when compared with other more teensy animals like birds and dragon flies. Nonetheless, we have developed vision systems that are capable of distinguishing the waves of invisible light like infrared and ultraviolet. Hyperspectral imaging systems differentiate colors of the spectral band, which enable technological visions to paint out the differences we humans cant see.

Hyperspectral imaging is a photography technique that collects particular information from the whole band of the electromagnetic spectrum. Compared to traditional color cameras, this imaging provides a digital image with more analytics and data. With this spelling out of the whole spectrum of each pixel in the image, observers may be able to better find objects, identify materials, and detect certain processes.

This imaging has assorted applications and uses in everyday life. Its proper utilization, though, requires proper understanding and a certain expertise. There are many processes and strategies used in interpreting resultant images, and they also have limitations. Certain knowledge includes recognizing the different fingerprints or spectral signature of different substances and materials.

The photography technique has myriads of application in the study of astronomy, medicine, pharmaceuticals, molecular biology, forensic science, remote sensing, food industry, agriculture, geology, and environmental and ecological studies. The branch of astronomy that specializes in photography use this imaging technique in differentiating and thereby identifying the colors of star clusters and galaxies. In molecular studies, hyperspectral systems emphasize the effect of dyes and stains in differentiating the parts and components of cells and microorganisms.

In forensics, HSI is used to dish out certain polemical evidences like fingerprints and blood samples. In the geosciences, geologists use this to track new oil fields. Surveillance and remote sensing operations in the military utilize this as well because it is useful in defense applications and target identification. In medicine, moreover, HSI is used to detect certain irregularities, such as tumors or foreign substances.

In environmental studies, HSI is applicable in the tracking of changes in the environment, like identifying pollution levels, spreading deforestation and desertification, and much more. Even in the food industy and in agriculture, multispectral imaging has left its mark. For instance, it is widely used in seed viability testing, which establishes a seedlings germination capacity. It is also important in food research by detecting nascent spoilage of fruits, identifying the freshness of fish, and sorting fruits and vegetables.

There are various imaging systems and products for different purposes and applications. For near conventional operations, you can use basic hyperspectral cams, which nonetheless have three hundred up to a thousand and seven hundred nano meters in range of the spectrum. Hyper spectral machine vision systems are for more quality and controlled applications. Depending on your venture, there are various machine visions to choose from. Choices include benchtop, outdoor, and airborne machine systems. As per their appellation, benchtop is used in the office or lab, outdoor out in the filed, and airborne up in aircrafts.

It's not just about the color. After all, hyperspectral imaging has progressed from unreliable research prototypes to accurate analytical instruments whose applications have ranged from detecting the bruise in your fruit to uncovering the secrets of the universe. It is a powerful tool that remarkably illustrates the potential of science and the importance of its development and application.
