The scan mirror sweeps the ground, projecting the energy through the tele-scope and onto the focal plane, which consists of four detectors in the TM or eight detectors in the ETM+. A scan-line corrector assembly compensates for the for-ward motion of the spacecraft during each sweep, returning adjacent sweeps to a parallel alignment.
