Meteors, Light Curves

Scientific paper

The dustball model of meteoroid structure would be expected to lead to short duration fluctuations on light curves, anomalous decelerations, and instantaneous light production over a significant spatial region. Detection of these features with conventional image intensified CCD approaches has proved elusive. We provide an overview of six improvements to traditional meteor light curve analysis in order to provide higher resolution: use of generation III image intensifier technology; digital recording techniques; digital image processing algorithms which separate the even and odd video fields; whole image background subtraction; analysis of pixel by pixel high resolution meteor light curves and utilization of coincidence and correlation techniques. Large aperture, long focal length systems are ideally suited to the studies mentioned here, and will be briefly mentioned.
