A human eye can see only three main colors that are Red, Green and Blue, which is known as the RGB configuration. All the other colors we see are the mixture of these colors.
A human eye cannot detect and see a color that is not comprised of these three basic colors.
The Image Replication Imaging Spectrometer (IRIS) system was developed by Andrew Harvey and his team at the Heriot-Watt University in the UK.
In contrast to the Human eye an IRIS system has 32 primary colors. The system works by dividing each image into 32 different snapshots and each of these snapshots are contain the light from one of its 32 spectral bands.
Thus this division allows the system to pick the features that cannot be distinguished by a human.
The 32 snapshots are then projected onto a detector allowing the device to analyze them simultaneously. After that all the features are then converted into false colors that can then be identified by the humans.
Many companies like Quinetiq and Selex are working on handheld version of the device, which can then be used to aid the armed forces. The device can detect the presence of mines or vehicles hidden in foliage.
The device also has its future in the medical tool market as such devices can easily distinguish between oxygenated and deoxygenated blood, which can further be used to detect some diseases.
