Abstract
An apparatus and method for estimating moisture content in a steam flow through a steam turbine is disclosed. At least a portion of a steam flow path through a turbine is illuminated using at least one laser assembly, and a plurality of digital images of the illuminated portion of the steam flow are obtained. The digital images are analyzed to measure an amount of light scattered in each digital image, and this analysis of each digital image is compared to estimate moisture content of the steam flow.
