Outline of Final Research Achievements

We studied a method for scanning laser Doppler velocimetry that doesn't require any moving mechanism in its probe to realize the equipment with a compact, reliable, and easily-handled probe for velocity distribution measurement. We developed techniques for directional discrimination and two-axis scanning. These techniques make it possible to apply the proposed velocimetry to various objects. In addition, we developed several types of miniaturized probes using free-space optics. We also investigated waveguide-type components for integration of the scanning laser Doppler velocimeter. As the results of the study, we have achieved the prospect of realizing an easily-handled scanning laser Doppler velocimeter for practical use.
