In the optical scheme of speckle pattern interferometer with the combined beams and speckle - modulated reference wave, the possibility use of a digital photo-camera for the study of vibration characteristics of gas turbine engines parts is revealed. The Peculiarities arrangements of camera in optical scheme are indicated. The use of high-resolution camera provides increased contrast of interference fringes and it expands dynamic range of vibration amplitudes during recording.
