| Project for analysing directional
effects in the thermal infrared range (8-14µm) for heterogeneous
scenes |
|
Participating laboratories: ONERA, CESBIO.
Goal: study
angle effects in the change of scale of thermo-optical values (brightness,
emissivity, temperature) on heteregeneous surfaces in the thermal
infrared range.
|
Means:
directional measurements using two infrared cameras (8-14 µm)
mounted on a directional bench, able to bear interchangeable
surface elements.
To complement the device, a reference surface is placed in
the scene (basin of water of known temperature) and directional
measurements of the incident atmospheric brightness are taken.
Campaign date: June-August 2001, the data are currently being analysed.
Participants: Laurent Coret (doctoral student at ONERA), Xavier Briottet (ONERA),
Keyvan Kanani (trainee at ONERA).
