Full spectral imaging is like having eyes that can see all the different colors that are around us. Just like how we see with our eyes, cameras and gadgets can also see things but they can only see certain colors.
A regular camera can only see a few colors like red, green or blue but with full spectral imaging, the camera can see way more colors than any human eye or regular camera can see.
It's like when you look at a rainbow and you can see different colors but with full spectral imaging, you can see even more subtle colors that you normally wouldn't be able to see.
It's really useful because it helps us to see things in a more detailed way. It's like having superpowers to see things that would normally be hidden to our regular eyes.
