  • Doppler radar sensing system for monitoring turbine generator components
    Patent number: 7095221
    Abstract: The invention provides a sensing system and a method for monitoring the damage to turbine components in a turbine generator. The sensing system comprises 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.
    Type: Grant

  • Method and apparatus of monitoring temperature and strain by using fiber Bragg grating (FBG) sensors
    Patent number: 6923048
    Abstract: A method and apparatus for monitoring changes in temperature or strain, using fiber Bragg gratings (FBG). The Method and apparatus is advantageously useful for the measurement under harsh conditions, such as by combustion turbines. The invention uses the wavelength shift which is caused by temperature or strain changes at the FBG and the changing of the refraction index of the fiber.

  • Optical monitoring of thermal barrier coatings
    Publication number: 20050063450
    Abstract: A system, a method and a component using thermally stimulatable substances for the temperature measurement of thermal barrier coatings are provided. The a thermal barrier coating comprises a stimulatable substance as high-lighter and a substance to adhere the thermal stimulatable substance in the coating. The stimulatable substance having emission lines which vary in response to a temperature of a coated component. For example, the present invention can be used in combustion turbines or combustion machines.
