Iran-Made Hyperspectral Camera Records Wide Range of Wavelengths

“A hyperspectral camera is a type of imaging sensor that records optical information in a wide range of wavelengths (beyond the visible range). Unlike conventional cameras, which are limited to recording only three color bands (red, green, and blue), these cameras receive hundreds of spectral bands in visible, near-infrared, and even beyond wavelengths,” said Peyman Soltani, the managing director of the knowledge-based company.

He explained that hyperspectral cameras are used in precision agriculture to identify plant health, pests and nutrient deficiencies, in geology and mining to identify mineral compounds and geological mapping, and in medicine and biology for medical imaging to diagnose diseases and examine biological tissues.

“This product is also used in the military and security field to identify camouflaged targets, border surveillance and security, in the industrial quality control sector to examine the quality of food, drugs and industrial products, and finally in environmental sciences to examine environmental pollution and ecosystem changes,” Soltani said.

A hyperspectral camera captures a scene’s light, separated into its individual wavelengths or spectral bands. It provides a two-dimensional image of a scene while simultaneously recording the spectral information of each pixel in the image.

The result is a hyperspectral image, where each pixel represents a unique spectrum. This unique spectrum can be compared to fingerprints. Since every material and compound reacts with light differently, their spectral signatures are also different. Just like fingerprints can be used to identify a person, the spectra can identify and quantify the materials in the scene.
