Minimize Sensor Description

The Return-Beam Vidicon (RBV) instrument was flown on board Landsat 1- 3. It consisted of three co-aligned television cameras, one for each spectral band (band 1: blue-green, band 2: yellow-red, band 3: NIR). RBV measurements of reflected solar radiation were only conducted in daylight. The three earth-oriented cameras were mounted to a common base, which was structurally isolated from the spacecraft to maintain accurate alignment. Each camera contained an optical lens, a 5.08 cm RBV, a thermoelectric cooler, deflection and focus coils, a mechanical shutter, erase lamps, and sensor electronics. The cameras were similar except for the spectral filters contained in the lens assemblies that provided separate spectral viewing regions.
