The latest hyperspectral imaging products for 2022
Hyperspectral imaging is a technique used to analyse a wide spectrum of light instead of just assigning primary colours to each pixel. The light striking each pixel is broken down into many different spectral bands to provide more information on the subject of the image.
There are three main types of spectral imaging techniques: spatial scanning uses push-broom scanners to read images over time; spectral scanning uses band sequential scanners to acquire images of an area at different wavelengths; and snapshot hyperspectral imaging, which uses a staring array to generate an image in an instant.
Hyperspectral cameras don’t just record images, they acquire a complete optical spectrum for each image point. They are used in a number of different applications spanning aero, astronomy, agriculture, molecular biology, biomedical imaging, geosciences, physics and surveillance. In addition, non-destructive and non-invasive monitoring is making hyperspectral imaging popular among other commercial and industrial applications, such as food quality testing, identifying counterfeits and fake art, sorting recycled material, automotive dashboard cameras and more. This list is predicted to grow, with many startups now entering into service-oriented businesses based on hyperspectral imageries.
In fact, according to the latest Hyperspectral Imaging – Market and Technology Forecast to 2030 report from ResearchAndMarkets.com, the global market for hyperspectral imaging will reach $49.4bn in 2030, up from $20bn in 2022.
