Exploring the Power of Hyperspectral Cameras in Solving Complex Challenges
Hyperspectral cameras are powerful tools used to address some of the most complex challenges in various industries. They work by capturing detailed spectral information from objects, providing insights that go beyond what the human eye can see. Here are some real-world problems where hyperspectral imaging proves invaluable:
-
Sorting High-Quality Ore
Extracting valuable metals from ore can be difficult when there is less than a gram of metal per ton. Hyperspectral cameras can differentiate between ore and waste rock, allowing for efficient sorting and cost-effective processing.
-
Early Detection of Diseased Plants
In agriculture, diseased plants often appear visually similar to healthy ones. Early identification using hyperspectral imaging can lead to significant cost savings by preventing the spread of disease and reducing crop loss.
-
Assessing Lobster Shell Age
The age of a lobster’s shell affects its flavour, shelf life, and price, but distinguishing between young and old shells visually is challenging. Hyperspectral cameras detect subtle chemical and physical differences, providing an accurate assessment of shell age.
-
Detection of Microplastics
Plastic pollution is a significant concern for both aquatic and terrestrial ecosystems. However, detecting small microplastics quickly is still challenging. A study published in MethodsX presents a method for rapidly identifying microplastics using hyperspectral imaging, taking advantage of advancements in hyperspectral camera technology.

Veins Detection in Humans
Reflectance data from the hands of 100 subjects with varying skin tones was collected using a Resonon Pika XC2 benchtop system, followed by the application of classification algorithms to detect veins in the HSI images.
-
Cooked Food
Hyperspectral imaging easily detects subtle colour changes in cooked food, providing a reliable method for assessing food quality.
-
Automated Solder Inspection
An automated system using a Pika L hyperspectral camera was developed to assess solder quality on circuit boards, capable of detecting defects, ensuring uniformity, and evaluating overall solder quality.
