Calibration facility for airborne imaging spectrometers
ESA currently builds the airborne hyper-spectral push broom imaging spectrometer APEX (Airborne Prism EXperiment) operating in the spectral range from 380 to 2500 nm. In the scope of the APEX projectExpand
APEX: current status of the airborne dispersive pushbroom imaging spectrometer
Recently, a joint Swiss/Belgian initiative started a project to build a new generation airborne imaging spectrometer, namely APEX (Airborne Prism Experiment) under the ESA funding scheme namedExpand
Calibration facility for airborne imaging spectrometers
TLDR
Calibration equipment and concepts for the airborne hyper-spectral push broom imaging spectrometer APEX (Airborne Prism EXperiment) are outlined and the high relevance to scientific objectives is highlighted. Expand
APEX: current status of the airborne dispersive pushbroom imaging spectrometer
Over the past few years, a joint Swiss/Belgium ESA initiative resulted in a project to build a precursor mission of future spaceborne imaging spectrometers, namely APEX (Airborne Prism Experiment).Expand
Imaging distance measurements using TOF lidar
This paper presents a new time-of-flight-based imaging lidar for measurements in the 5-100 m range. The paper describes the concept of the device, shows the design of the time-to-digital converterExpand
A new laboratory for the characterisation of hyperspectral airborne sensors
A new facility designed to characterize the spectral, radiometric and geometric properties of hyperspectral airborne sensors was established at the German Aerospace Center (DLR) in Oberpfaffenhofen.Expand
Refractive-index changes caused by proton radiation in silicate optical glasses.
We have studied experimentally, by using a differential interferometric technique, the effect of proton radiation on the refractive index of commercial (Schott) silicate crown glasses, BK7 and LaK9,Expand
THE AIRBORNE IMAGING SPECTROMETER APEX: FROM CONCEPT TO REALISATION
APEX (Airborne Prism EXperiment) is a project of the European Space Agency ESA focusing on high accuracy simulation, calibration and validation for spaceborne remote sensing instruments. TheExpand
Design And Performance Of A High Resolution, High Accuracy Automatic Autocollimator.
Moller-Wedel has developed a very high accuracy angle measuring instrument. The angular resolution of the instrument exceeds 0.005 arcsec (-25 nano-radians). The repeatibility and absolute accuracyExpand
Dynamic holography for the space qualification of large reflectors
The next generation of infrared - sub mm space telescopes requires reflectors with large dimensions, high quality and, according to weight issues, are based on composite or new materials technology.Expand
