1. An apparatus for the non-destructive monitoring of a coated metallic turbine component, comprising:
- an electromagnetic wave generator that generates an electromagnetic wave;
a transmitter that transmits the generated electromagnetic wave from a first turbine component;
a second turbine component that receives the transmitted electromagnetic wave and reflects the electromagnetic wave;
a receiver that receives the reflected electromagnetic wave; and
a processor that interprets the received electromagnetic wave.

19. A method for real time monitoring of damage to a turbine component in an operating turbine generator, comprising:
-
transmitting a signal in the form of an electromagnetic wave from a first component;
receiving the signal transmitted from the first component by a second component;
reflecting the transmitted signal off the second component back to the transmission source;
processing the transmitted and reflected signals to determine if the turbine component is damaged. - View Dependent Claims (20, 21)
