A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.

Multispectral image of Bek crater and its ray system on the surface of Mercury, acquired by MESSENGER, combining images at wavelengths of 996, 748, 433 nm. The bright yellow patches in other parts of the image are hollows. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.

Spectral imaging is imaging that uses multiple bands across the electromagnetic spectrum. [1] While an ordinary camera captures light across three wavelength bands in the visible spectrum, red, green, and blue (RGB), spectral imaging encompasses a wide variety of techniques that go beyond RGB.
In the above graph, the first bar is a key to the electromagnetic radiations that either, don't or do penetrate the earth's atmosphere. Y is for yes and N is for no. Y is for yes and N is for no. Although some radiations are marked as N for no in the diagram, some waves do in fact penetrate the atmosphere , although extremely minimally compared ...
Hyperspectral imaging collects and processes information from across the electromagnetic spectrum. [1] The goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes. [2] [3] There are three general types of spectral imagers.
The electromagnetic spectrum encompasses all electromagnetic radiation - ranging from radio waves through microwaves, infrared, visible light, ultraviolet, x-rays and gamma rays in order of increasing frequency.
