[edit] Summary

The key component for hyperspectral imaging (HSI) is the HSI sensor.

The HSI sensor receives light that is reflected from below and converts it to electrical signals. It accomplishes this with the following components:

   * Lenses that focus the incoming light
   * A slit that limits the incoming light stream to a very thin but wide beam
   * A diffraction grating that disperses the thin, wide beam into its spectra
   * Photo-receptors that collect light in specific wavelength ranges (bands) and convert the band intensities to electrical signals

A very simplified diagram of the HSI sensor is shown below.
