摘要

An experimental demonstration of helicopter plume detection by using a range-resolved, narrow-bandwidth, noncoherent laser Doppler velocimeter is presented. The laser Doppler velocimeter detects incoming Doppler-shifted signal photons by using the sharp spectral transmission features in a Faraday magneto-optic atomic line filter.
