What is Hyperspectral Imaging System?

Hyperspectral imaging has been immensely growing admired over the last few decades in various industries that involves military, industrial, scientific arenas and many more. The ability to precisely characterize the colour of a viewed item, whether a camouflaged vehicle, a bruise on an arm or on fruit, or a wide swath of vegetation, allows the user to make informed decisions only dreamed of in the past. This imaging system is a technique that analyses the wide spectrum of light rays instead of just any single ray or colour. The multispectral imaging might evaluate an image in three or four colours (red, green, blue and near-infrared (NIR), for example), hyperspectral imaging breaks the image down into tens or hundreds of colours.

Where does the Hyperspectral Imaging Device come in handy?

Standard colour cameras can only capture the spectral channels associated with the three primary colours – red, green, and blue – and thus create hyperspectral images that are much more complex and accurate. As a result, hyperspectral imaging is ideal for any situation in which images must cover a wide area of terrain and encode a large amount of data in a single view. In cutting-edge military, ballistics, and satellite applications, hyperspectral imaging is commonly used. It's also been used in the lab for medical and biophysics studies, as well as in industrial quality control.

What is the Method of Using a Hyperspectral Camera to Capture Images?

In the so-called "pushbroom" mode, hyperspectral imaging is performed line by line. Until working on the next line, a very thin spatial line is captured and broken into its spectral components. This amount of processing is normally achieved in a single sensor array. One dimension of the second sensor array is dedicated to spectral separation, while the other is used for single-dimensional imaging. Splitting the work allows for quicker processing of complex image data over a wider field of view.

Hyperspectral Imaging Device Important Applications:

Remote sensing: It is essential to differentiate earth surface features in remote sensing technology because each feature has a different spectrum band. A multispectral satellite, such as Landsat 7, can capture images in a variety of bands. However, a multi spectral imaging satellite can capture the earth's surface in more than 200 bands, enabling scientists to discern objects that were previously difficult to distinguish using multi spectral imaging due to spectral resolution.

Analysis of Seed Viability: One can decide whether or not certain seeds are viable by using a hyperspectral picture and plotting the reflectance spectrum. The seed will appear similar to the naked eye, but the hyperspectral image will expose its viability.

Biotechnology: The use of hyperspectral technology in biological and medical applications has increased in popularity. Obtaining data that can be used in the laboratory is simple and fast. They're mainly used in wound analysis, fluorescence microscopy, and cell biology studies.

Monitoring the Environment: Hyperspectral imaging is becoming increasingly common for monitoring environmental changes. It's widely used to find out how much CO2 is emitted into the atmosphere, chart hydrological formations, monitor pollution levels, and more.

Forensic Science: Hyperspectral imaging technology can discern fine spectral resolution, making it perfect for use in forensic laboratories. It can be used for a number of purposes, including questioned document analysis, fire investigation, bloodstain visualisation, fibre comparison, gun powder residue visualisation, duct tape inspection, fingerprint enhancement, and TLC plate visualisation, among others. Hyperspectral imaging, for example, may distinguish between dark spots and bloodstains. When it comes to solving a crime case, this form of distinction is key.

Final Thoughts:

This hyperspectral system aids in allowing accurate and consistent colour and material differentiation. This device can be useful in a number of ways. The demand for hyperspectral imaging systems is being guided by rising funding and investments, as well as growing industrial applications of hyperspectral imaging.
