Detection of small particles in fluid flow with a self-mixing laser

Not Accessible

Abstract

Highly sensitive, real-time detection of small particles in fluid flow has been demonstrated by using a laser-diode-pumped, self-mixing thin-slice Nd:GdVO4 laser. Power spectra of modulated laser output, reflecting the velocity distribution of liquid flow, due to the scattered light from small particles in fluid flow were observed.
