[The] Multi-Spectral Scanner... is a line scanning device which records from four bands, two in the visible and two in the near infrared spectral bands. The system is comprised of a telescope, a mirror which reflects ground radiation onto a bank of 24 electro-optical sensors, band filters and a sampling system, an internal calibration system and various devices which ensure an orderly stream of digital data for each pixel and spectral band. It images six scan lines in each of the four spectral bands simultaneously giving a 24 scan-line total.
