Abstract

In near-wall measurement appl ications (viz ., boundary layer flow characterization) of the laser Doppler velocimeter, light scattered from the wall tends to swamp the scattered light from the flow-tracing particles. This reduces the signal-to-noise ratio (SNR) . This paper describes a technique to improve the SNR by using a microscope objective in the receiving optics train.
