Monochromatic heterodyne fiber-optic profile sensor for spatially resolved velocity measurements with frequency division multiplexing.
Pfister T, Büttner L, Shirai K, Czarske J. Pfister T, et al. Appl Opt. 2005 May 1;44(13):2501-10. doi: 10.1364/ao.44.002501. Appl Opt. 2005. PMID: 15881057
A frequency-doubled Nd:YAG laser and a fiber-optic measuring head were employed, resulting in a portable and flexible sensor. In the center of the measurement volume of approximately 1-mm length, a spatial resolution of approximately 5 microm was obtained. ...Small velocit …
