Simplified Integral Field Unit's (IFU) operation based upon a 3X3 fiber optics array. In the diagram, the light from the image of the galaxy is transported through optical fibers to a spectrograph (indicated by prism). A spectrum is produced by each fiber and captured on a large CCD detector. Artwork by Jon Lomberg. Photo credit: "Gemini Observatory".
