APPLICATIONS OF HYPERSPECTRAL IMAGING
During the last three decades, hyperspectral imaging (HSI) has grown from being an expensive research-oriented technique to one that is applicable for a wide range of scientific and industrial applications such as in food production, during forensic analysis, art and art conservation, environmental monitoring, and many others.
The ability of hyperspectral imaging to identify and quantify materials in a non-destructive and non-invasive manner has led to uptake in many new applications, and has allowed it to be developed into a fast and reliable technique to - for example - measure, inspect, grade and sort food products, analyse chemical composition of pharmaceuticals, analyse degradation in the most fragile artwork, and even identify rare earth elements based on their spectral features.
Some of the industries we have supplied hyperspectral systems for include:
- Heritage science
- Food quality and security
- Forensic science
- Chemical imaging
- Colour measurement
- Phenotyping
- Change detection
- Industrial quality control inspection
- Materials identification
- Medical and pharmaceuticals
- Recycling
To find out more about these various academic and commercial applications and how they are using hyperspectral imaging, explore the materials below and find out how we could help you use hyperspectral imaging and optical spectroscopy to enhance your own research or business.
FOOD QUALITY AND SECURITY
Whilst size, shape, colour, and surface texture of food can be easily measured by conventional machine vision systems, the prediction of many other parameters, such as fat, sugar and moisture content, protein, material homogeneity, or materials hazardous to the consumer can all be detected quickly and simultaneously by hyperspectral imaging systems.
HSI implementation into food production systems also enables accurate high speed sorting. The spectral signature (much like a human "fingerprint") of the material, combined with the spatial information, allows excellent determination of substandard product, contamination, presence of foreign bodies, as well as defects by colour, shape and size, as well as package seal integrity inspection.
Our advanced machine learning and classification algorithms built into our
software
then allow discrimination methods to be set up for the process line and the output can be applied in real time to interface to gravity, paddle separators, or robotic arm pickers etc.
HERITAGE SCIENCE & ART CONSERVATION
Hyperspectral imaging has become one of the key analytical tools for evaluating historical documents and artworks.

Working with even the most fragile and precious of examples, HSI can accurately, efficiently, and most importantly safely identify the chemical composition of artwork i.e. the pigments/binders used, its degradation or change over time, its authenticity, and even the technique used by the artist in creating the works.
Our ClydeHSI
art scanning solutions
are designed as complete, end-to-end solutions that make robust, reliable, accurate and repeatable hyperspectral measurements in seconds, and are fully configurable to accommodate documents, 3D art structures and paintings of all shapes and sizes.
Each instrument is delivered calibrated and with a certificate of conformance. The spectral calibration is made, and the image performance tested and demonstrated using calibration targets.
OTHER HSI APPLICATIONS
The applications of hyperspectral imaging are wide ranging and ever-expanding. As well as our specialist areas above, ClydeHSI has delivered complete hyperspectral imaging systems in a diverse range of application areas:
As well as having in experience in many areas, we are constantly looking to expand our capabilities. If you think hyperspectral imaging could assist you in your application which is not listed above, or if you are involved with one of the above applications and want more information, please contact us.
