Zusammenfassung:	To provide a steam turbine droplet measuring method capable of measuring at least one of the grain diameter and velocity of droplets even in a case where the flow of steam and the flow of the droplet are different.SOLUTION: A steam turbine droplet measuring method for measuring at least one of the grain diameter and velocity of droplets generated inside a steam turbine, comprises: a laser beam irradiation step of irradiating the inside of a turbine cabin with laser light from the outside of the turbine cabin of the steam turbine through a window provided in the turbine cabin; and a droplet measuring step of radiating the laser beam and detecting scattered light scattered from the droplets to measure at least one of the grain diameter and velocity of the droplets.SELECTED DRAWING: Figure 1 【課題】蒸気の流れと液滴の流れが異なる場合であってもその液滴の粒径及び速度の少なくとも一方を計測可能な蒸気タービン液滴計測方法を提供する。【解決手段】蒸気タービンの内部に発生する液滴の粒径及び速度のうち少なくとも一方を計測するための、蒸気タービン液滴計測方法であって、蒸気タービンのタービン車室の外部からタービン車室に設けられた窓を介してレーザ光をタービン車室の内部に照射するレーザ光照射ステップと、レーザ光を照射され記液滴から散乱した散乱光を検出して、液滴の粒径及び速度のうち少なくとも一方を計測する液滴計測ステップと、を備える。【選択図】図１
