Multiple-line laser Doppler Velocimetry
Abstract
The luminosity of an LDV diagnostic suitable for study of the high strain-rate motion of solids, as in shock-wave experiments, is presently increased by an order of magnitude through the use of a broadband pulsed laser that is coupled to a Fabry-Perot device which acts as a spectrum modulator/demodulator. This instrumental configuration facilitates the analysis of weakly reflective materials' behavior during shock loading. Illustrative experimental results are presented.
