Abstract

New optical detection systems are being developed which combine conventional passive photometry with advanced data processing and statistical analysis methods. These crossed-beam detection systems can continuously monitor meteorological parameters in rocket or aircraft environments. The outputs from several photometers are analyzed by cross correlation techniques to retrieve the transit times or transit distance of light emitting, absorbing, or scattering particles between the photometer lines of sight. These transit times and distances are then transformed into wind components and turbulence levels for preselected altitudes. A continuous near real time display of these meteorological parameters is also under development.
