Das Mehrstrahl-Spektralradiometer HYDRA: Entwicklung und Einsatz zur Charakterisierung des natürlichen Lichtfeldes unter und über Wasser und zur Bestimmung von Wasserqualitätsparametern

Ein Spektralradiometer für den Schiffseinsatz wurde konzipiert und aufgebaut, das die Strahlungsverteilung über 9 auf einer Tauchsonde und Überwassereinheit angeordnete Lichtkollektoren mit hoher spektraler und radiometrischer Auflösung im Bereich 400-825 nm erfaßt. / Preis: 27,10 + MwSt

From lab to space: Fourier transform spectroscopy at DLR, invited lecture, "Fourier Transform Spectroscopy and Optical Remote Sensing of the Atmosphere

High accuracy laboratory measurements for the spectroscopic database of atmospheric constituents were performed using high-resolution FTS. A new rugged medium-resolution field FT instrumetn was developed. The combined expertise is applied for space remote sensing

Spectroscopic Measurements from Space with the FOCUS Sensor System to analyse Gas and Smoke Properties of high Temperature Events

Operated on the International Space Station ISS the FOCUS sensor system will autonomously detect and analyse high temperature events like forest and bush fires, volcano eruptions or coal seam fires. The system consists of imaging sensors for the visible and infrared spectral region as well as a Fourier transform infrared (FTIR) spectrometer. The heritage of FOCUS, the DLR imager BIRD and FTIR spectrometer MIROR, are presented. Modifications incl. high accuracy radiometric calibration are described. Three dimensional distribution of temperatures, combustion gas concentrations and smoke aerosoles will be retrieved by inversion of radiative transfer models combined with an unique fusion of the FOCUS spectral and imaging data
