IR Cameras in EUSO Preliminary work from : AnnaAnzalone, Francesco Isgrò, PedroAbreu, Mario Pimenta, Masahiro Teshima M. Pimenta Munich 2003
Goal ISS EUSO • Evaluation of the EUSO Effective Field of View: • Average cloud coverage within • operational time • Cloud parameter evaluation at the occurrence of an event: • Cloud-top height evaluation • …..
Stereo visioncloud height • InfraRed camera(s) in EUSO • Stereo vision provided by the movement (pos. 1, 2) • Pattern Recognition(different views of the same cloud) + geometry cloud height H • resolution: 1 2 /| =30° = 0.1% H 500 m Cloud! H Earth!
Tests on ATSR data • Along-Track Scanning Radiometer (ATSR-2) on the ERS-2 satellite: • Altitude 780 km, velocity 6.7 km/s • 2 observations with 120 s separation First Test : Use of a differential method to evaluate the motion field on a pixel basis:
A Possible camera? m ~ 5 Kg
