An optical multisensor combining mid IR laser scanner, and near IR multispectral scanner (LIMES)

The application possibilities of thermal infrared laser spectroscopy for remote sensing were investigated in laboratory and flight campaigns. For the flight measurements, a profiling laser spectrometer with 2 tunable CO2 lasers was used. In the laboratory, the reflection spectra of minerals, soils, rocks, vegetation, water, moistened surfaces and oil spills on water were taken. Flight measurements (soil, rock surfaces, water, irrigated field, vegetation, asphalt) agree with the laboratory results (in-situ measurements). Based on these results, a program for the development of an optical multisensor, combining mid IR laser scanner and near IR-multispectral scanner was started.
