Abstract

When performing direct-contact laser-Doppler flowmetry on experimental flow models, the power spectra of the detector signal can be obtained by homodyne or by heterodyne detection. Especially with uniformly moving probe particles coherence effects are observed, leading to changes in the width of the power spectrum. Due to destructive interference effects at the detector surface, in the measured homodyne spectra the contribution of relatively high Doppler frequencies is suppressed compared with that of lower frequencies. This results in spectra which are narrower than expected theoretically. This effect allows us to investigate the importance of the relative amount of coherence areas at the surface of the detector.
