Summary: | A further clarification of the volume from which data originate in the dual scatter laser Doppler velocimeter is presented. Several factors are noted that specify the primary dimensions of the probe volume which in some cases are totally specified by the collector optics. It was found experimentally that the lens aperture of the light collecting optics has a primary effect on the volume from which data originate. An equation is derived for reducing this data volume for both the on-axis and off-axis cases. Experimental verification is presented and compared to the derived equation.
