Small Grant for Exploratory Research: A New Optical Tech- nique for Flow Measurement

根据探索性研究小额赠款， 将建立一种新型的非侵入式激光测速系统 和测试。 该系统跟踪激光照射的颗粒 通过一个非常小的光电二极管阵列， 电子时钟 多维速度能力是 可通过单梁和合适的布置来实现 二极管阵列 该系统在原理上比传统系统简单得多 LDV流量诊断系统。 如果一个可行的系统， 这个想法是可以发展的，它将提供一个坚固的，便携的， 和廉价的替代LDV系统。

Under a Small Grant for Exploratory Research, a pilot model of a novel non-intrusive laser velocimeter system will be built and tested. The system tracks laser illuminated particles across an array of very small photodiodes and times them with an electronic clock. Multi-dimensional velocity capability is achievable with a single beam and suitable arrangements of diode arrays. The system is in principle much more simple than conventional LDV flow diagnostic systems. If a workable system based on this idea can be developed, it would offer a rugged, portable, and inexpensive alternative for LDV systems.
