Spectral imaging

Spectral imaging is like using special glasses to see things that we couldn't see with our normal eyes. Just like how we use different colors to see different things, like green for grass and blue for the sky, spectral imaging uses a range of colors that we can't see with our eyes to see more details in an object.

To use spectral imaging, we need a special camera that can capture light in a lot of different colors, usually in the form of wavelengths. Think of the colors of the rainbow, each of which has its own wavelength. The camera can then take all of these colors and make a picture out of them.

Imagine you are looking at a red apple. If you take a normal picture of it, you'll just see it as red. But with spectral imaging, the camera can capture all the different colors that make up the red apple, allowing us to see details that we couldn't see before, like the different shades of red, or even other colors that are present but hidden from our eyes.

Scientists use spectral imaging to look at things like plants, rocks, and even the atmosphere. It allows them to study different materials and chemicals, and to see patterns and structures that are only visible with different wavelengths of light.

In summary, spectral imaging is like using special glasses to see more details and colors that we can't see with our normal eyes, by capturing light in different wavelengths with a special camera.
