Abstract
To investigate gas-turbine engine parts vibration speckle interferometer has been developed, an optical scheme of which includes two sources of laser radiation with different wave length. This has made it possible to increase vibration measurement accuracy due to experimental points number increase. A diagram of the 7-th stage compressor blade inlet edge vibratory displacements has been plotted according to the second flexural mode using speckle interferograms obtained at different length of the applied laser radiation.
