8 Reasons to Invest in Hyperspectral Imaging

March 21, 2022

It's no secret that high-quality data helps to solve difficult problems. Buying a hyperspectral imaging system enables the collection of hundreds of spectral bands in order to better distinguish plant species, surface mineral deposits, and subtle changes to the environment over time. Hyperspectral imaging can even identify variations in antiquated artwork and historical documents. 

How can you ensure that the purchase you make will provide years of reliable data collection and analysis? Read on to learn the 8 reasons why you should invest in hyperspectral imaging.

  1. Instead of analyzing light at each pixel, hyperspectral imaging can acquire and analyze a portion of the light spectrum that is invisible to the naked eye in extremely fine detail. The spectral signature of an object is unique and can be detected and separated from the rest of the image. 

  2. The human eye cannot distinguish the difference between, say, a pure purple color and a mixture of blue and red colors. Hyperspectral imaging can.

  3. Using a hyperspectral imager can be likened to having hundreds (or thousands!) of single-point spectrometers analyzing an area to gather data on chemical and spatial variations. 

  4. There are a multitude of applications that can benefit from the visualization and classification of chemical variations. Artwork, exposed minerals, product quality, crop health, and food inspection are all areas where hyperspectral imaging can be applied.

  5. While a 4- or 5-band multispectral imaging system can detect more variations than the 3-band red, green, and blue human vision, a 60- or 300-band HSI system can provide even better analytics and more precise material
    characterization than a multispectral imaging system.

  6. Non-invasive data acquisition of an object or spatial area is extremely valuable to scientists, biologists, geologists, and even historians. A hyperspectral imaging sensor can be placed on UAVs, manned aircraft, or satellites. Remote sensing using HSI enables the collection of data in dangerous or otherwise hard-to-reach areas. The data collected can then be analyzed and used to make important decisions regarding the environment and defense and security threats.

  7. Acquiring data in real-time has historically been challenging in machine visioning environments (i.e. food inspection assembly lines). Rapid and precise measurements need to be communicated to other industrial platforms. By having the ability to collect and identify spectral signatures in real-time, companies can boost their quality inspections to safer levels. Hyperspectral imaging in machine-visioning environments can also lead to production efficiency by increasing throughput in process manufacturing. Headwall exceeds in managing the integration of advanced systems by pairing multispectral imaging with hyperspectral imaging sensors.

  8. Color management is critical to industries such as automotive, textiles, and paints. Quality control in real-time enables these industries to assure uniform color matching. 

To summarize, different substances with unique spectral signatures, whether viewed from the air, on the ground, or in the laboratory environment, can be imaged, classified and visualized using sophisticated yet intuitive software programs so that you can see on the computer screen what you might not be able to distinguish with your eyes.

Headwall has a solid track-record of providing industry-leading products and solutions, with over 40 years experience in diffractive optics. We have thousands of products being used by millions of customers worldwide, and we provide solutions from OEM components and subassemblies - to fully integrated, intuitive instrument systems that are designed to work out of the box.
