The SIV project - the intensified video cameras
Two basically identical video cameras were used to get stereoscopic
views of the meteors and thus their true path within the atmosphere:
-
IMCA (Intensified Meteor Camera) - operated by Detlef
Koschny - click here for a picture
-
VideoMet (Video camera for Meteor observation) - operated
by Andre Knöfel
The cameras were designed and integrated by Mirko Nitschke and Sirko Molau
from the International Meteor Organisation,
see e.g. Computer
Based Meteor Search - a New Dimension in Video Meteor Observation,
WGN
- Journal of the International Meteor Organization" 22-4 (1996), p.119.
The cameras have the following characteristics:
-
50 mm f/0.75 lens (Rayxar)
-
microchannel plate image intensifier (Hamamatsu compatible)
-
Single board video module, 25 frames per second (Conrad electronics)
-
Image recording on standard VCR
-
time insertion by "Cuno's time machine" into the videosignal, fed by a
DCF clock
-
Apparent field of view (FOV) about 20°
-
Limiting magnitude better than 7.5 mag
-
Data evaluation: currently, detection of meteors by visually analysing
the tapes - automatic
detection planned
-
Possible meteor data to be obtained: Position, time, velocity, brightness
(after calibration)
