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.

在探索性研究的小额拨款下，一种新型非侵入式激光测速仪系统的试点模型将被建立和测试。该系统通过一组非常小的光电二极管跟踪激光照射的粒子，并用电子钟对它们进行计时。通过单光束和适当的二极管阵列布置，可以实现多维速度能力。该系统在原理上比传统的LDV流量诊断系统简单得多。如果基于这个想法的可行系统能够被开发出来，它将为LDV系统提供一个坚固、便携和廉价的替代方案。
