| Outline of Final Research Achievements |
To establish a method for measuring a two-dimensional cross-sectional velocity distribution precisely and densely with a compact and reliable probe, we studied laser Doppler velocimetry using a combination of non-mechanical scanning and simultaneous multipoint measurement based on spatial encoding. We developed a technique for dense velocity distribution measurement with 48 measurement points and a signal acquisition/processing system for automated and high-speed measurement. In addition, we investigated a miniature probe using compact bulk optics and a waveguide-based integrated probe.
