The human eye can distinguish only three primary colors of visible light. This is in contradistinction to computer vision systems, which are capable of distinguishing a greater lineup of color channels. Hyperspectral imaging systems are capable of differentiating spectral domains from infrared to ultraviolet, which enable machine visions to display the reflectance differences that humans cannot 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 various uses and an established importance in society. However, there are certain methods and strategies that go into accurately interpreting the data, so technological sagacity is still a premium. One of the basics of HSI is the recogniton of the unique fingerprints or spectral signatures of certain substances and materials. For example, a microbe has a certain signature, and a human cell or burlap fiber have corresponding different signatures.
Multispectral imaging has sundry uses in astronomy, molecular biology, pharmaceuticals, forensics, geosciences, remote sensing, medical diagnosis, food and agriculture, and ecological and geological studies, among others. Astrophotography uses this technique to highlight the colors of certain nebulae and galaxies. In microscopy, it is used to emphasize the contrast already provided by stains and dyes.
In the area of forensic sciences, HSI identifies convicting evidence like blood and DNA samples and fingerprints. In the brach of medicine, HSI is used to identify certain aberrations such as tumors and foreign elements and substances that cause diseases. Remote sensing and surveillance operations by the military forces use this imaging as well in order to pinpoint targets and locations. In geology and petrology, this is used to scale topography or track undiscovered oil and gas fields.
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.
For imaging systems and products, there are hyperspectral cameras, which can cover three hundred up to one thousand and seven hundred nanometers in spectral range. If youre after automated sorting and quality control applications, theres the hyperspectral machine vision systems. There are benchtop, outdoor, and airborne systems. Benchtop is for laboratory and industrial use, the outdoor is mounted on a tripod for field use, and the airborne is designed for UAVs and manned aircraft.Accessories like objective lenses, lighting fixtures, analysis software, and scanning stage options are already provided for.
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.
