HRV SPOT camera detection unit - Optical and radiometric characteristics
Abstract
The main features of the detection unit for the High Resolution Visible (HRV) push-broom cameras of the SPOT observation satellite are summarized. Operating from a 830-km high orbit, the cameras will view a strip of the earth 60 km wide with a 10-m resolution. The main functions of the detection unit are to convert optical signals into electronic signals, to separate the four spectral bands, and to constitute 6000-pixel detection lines. The main optical and radiometric characteristics are presented: spectral sensitivity, responsivity and spatial uniformity, signal to noise ratio, modulation transfer function, and geometric characteristics related to image quality. The first flight models have been tested and delivered, and test results give confidence that flight performance will be as required.
