Paper Abstract

The imaging pushbroom scanner MOS measures the spectral radiance of the backscattered radiation of the earth surface in the VIS/NIR spectral region from orbit altitudes. The two main problems, the investigation of ocean/land and atmospheric properties, require a modular optomechanical and -electronical spectrometric device: MOS-A especially for data acquisition in the absorption band of the atmospheric oxygen in 4 spectral channels with 1,4 nm bandwidth and MOS-B with 13 channels of 10 nm bandwidth between 0,4 micrometers and 1,0 micrometers . The spectral and radiometric properties of MOS are chosen with respect to the spectral characteristic of the upwelling radiation, which is influenced by the object spectral reflection function. They are a compromise between the dominant measuring quantities like radiometric, geometric and time resolution requirements. These problems in connection with the design and calibration concepts will be discussed.
