摘要
PROBLEM TO BE SOLVED: To provide a steam turbine liquid droplet measuring apparatus capable of measuring a diameter and a speed of a liquid droplet that is generated within a steam turbine more easily and more accurately and a steam turbine using the same.SOLUTION: A steam turbine liquid droplet measuring apparatus is provided with a hollow tubular member 20 which is disposed to penetrate a casing 101 of a steam turbine 100; converts laser light 4a oscillated by a laser light oscillation unit 4 and passing via the tubular member 20 into laser sheet light 8 formed into a sheet shape and radiates the laser sheet light 8 into a working fluid within the casing 101; transmits reflection light 32 and internal refractive light 33 obtained from a liquid droplet 31 within the working fluid by radiation of the laser sheet light 8 to outside of the casing 101 by a bore scope 10 via the tubular member 20; and comprises an image pickup unit 21 which images the obtained reflection light 32 and internal refractive light 33 from the liquid droplet 31 and which generates an interference fringe image based on a phase difference.SELECTED DRAWING: Figure 1
