The Operational Land Imager (OLI)

The Operational Land Imager (OLI), built by the Ball Aerospace & Technologies Corporation, will fly on the Landsat Data Continuity Mission (LDCM). OLI will measure in the visible, near infrared, and shortwave infrared portions of the spectrum, with an improved signal-to-noise ratio compared to past Landsat instruments. The opening facing the left of the photo will point at the Earth, and the opening on the right is for pointing towards the sun, to calibrate the instrument.
