The "Reflective Optics System Imaging Spectrometer" (ROSIS) is a compact, programmable imaging spectrometer based on a CCD matrix
detector array. The optics of the system is made of reflective components only. The present horizontal resolution is 500 pixels across-track for
a one-camera system with 32 selectable channels out of 85 within the spectral range 430 - 850 nm. The spectral mode permits all 85 channels
to be read using every third across-track pixel. The instrument has been designed specifically for the monitoring of water colour and of natural
chlorophyll fluorescence in order to derive concentrations of phytoplankton chlorophyll and other pigments, suspeded matter and yellow
substance, and to map their horizontal distribution in the sea. However, its high spectral resolution (of <5 nm) and flexibility also permits
new applications in the remote sensing of atmospheric parameters such as cloud-top height and vegetation monitoring. An airborne prototype
of ROSIS is being jointly developed at present by MBB, GKSS and DFVLR. The instrument concept, the data processing system and the
scope of application is discussed.
