Laser-Based Steam Moisture Measurement via Light Scattering

The patent replaces traditional mechanical or contact-based measurement methods with an optical measurement system. A laser assembly emits light through the steam flow, and image sensors capture the transmitted light patterns. This optical substitution eliminates physical contact with the steam, making the measurement non-invasive while maintaining high accuracy through light absorption and scattering analysis.

The patent introduces light as an intermediary medium to measure steam quality indirectly. The laser beam serves as a mediator that interacts with the steam flow without disrupting it, carrying information about moisture content through its transmission characteristics. This intermediary approach allows accurate measurement while preserving the natural steam flow state.

The patent replaces complex mechanical measurement devices with a simpler optical system consisting of a laser assembly and image sensors. This substitution reduces mechanical complexity while enabling accurate steam quality measurement through optical property analysis, thereby lowering both device complexity and associated costs.

The patent uses image sensors to capture optical copies or representations of the steam flow's light transmission characteristics. Instead of directly measuring physical steam properties with complex devices, the system creates optical images that can be analyzed to determine moisture content, simplifying the overall measurement apparatus.
