Abstract

Methods for filtering signals in three-component laser Doppler anemometers for separating signals in optical paths of complementary devices are considered. A method is proposed for suppressing the mutual influence of signals based on the use of monochromatic sources of optical radiation with close wavelengths and bandpass optical filters. The possibility of implementing the proposed method of signals optical filtering in three-component laser Doppler anemometers using modern semiconductor laser diodes and bandpass optical filters is shown.
