Abstract
In the atmospheric applications of a Laser Doppler Velocimeter (LDV), two distinct methods have been reported.1 -4 The first method utilizes light with a wavelength of about 0.5 micrometer in conjunction with dual scatter (DS) LDB illuminating techniques.2-4 The second method uses light of 10.6 micrometer wavelength and local oscillator (LO) LDV illuminating techniques. 1,4 There appears to be some question as to which system is the most advantageous to use.2 The purpose of this paper is an attempt to adjudicate the claims made for each method by presenting equations and examples that will give some quantitative basis for LDV system selection and performance criteria in atmospheric research. For the comparisons made, the results show that specific ranges and conditions exist where performence of one method is superior to that of the other.
