Double wavelength speckle interferometer for the research of static deformations of gas turbine engine parts
Two coherent radiation sources with the wavelength of 532 nm and 632.8 nm are used in a speckle interferometer optical arrangement with combined beams and speckle-modulated background wave. The reference beam is formed with the help of a diffuser located in front of the object under investigation. T...
