The utilization peculiarities of digital camera in the optical scheme of speckle pattern interferometer for vibrometry of gas turbine engines parts

Бесплатный доступ

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.

Vibrometry, holographic and speckle – interferometry, speckle pattern, speckle-noise
