DOPPLER MEASUREMENTS OF RELATIVE AIR-FLOW VELOCITIES USING CO2-LASERS

The series of articles that follow addresses the design, investigation , and applications of laser Doppler velocimeters (LDVs) using CO2 lase rs. The following topics are discussed: physical aspects of the intera ction of a sensing laser beam with atmospheric aerosols; an analysis o f the metrological characteristics of an optical heterodyne converter; problems in the detection and processing of secondary Doppler signals ; the element base of LDVs; aspects of the metrological support of LDV design and operation. In addition to general problems in the construc tion and investigation of LDVs, special types of laser Doppler measure ments are discussed in some of the articles.
