Nondestructive Evaluation of Automobile Tires by Electronic Speckle Pattern Interferometry
نویسندگان
چکیده
Electronic speckle pattern interferometry (ESPI) was used for the evaluation of mechanical properties of automobile tires. The tire on wheel disc was fixed on the holder and its vibration was generated by loudspeaker. Vibrational field of the whole tire was visualized by ESPI and recorded into PC. Natural frequencies of various vibrational modes were measured and results were compared with those obtained by Doppler’s vibrometer.

We describe three different interferometric techniques (electronic speckle pattern interferometry, digital holographic interferometry, and digital shearography), using a long-wave infrared radiation produced by a CO(2) laser and recorded on a microbolometer array. Experimental results showing how these methods can be used for nondestructive testing are presented. Advantages and disadvantages of...

A novel nondestructive testing (NDT) method where measurement of large object deformations using temporal evolution of the speckles in speckle interferometry is reported. Basic principle of the method is continuous object deformation is introduced and the fluctuations in the phase of the speckle as intensity modulation is recorded. Acquiring a large number of frames of the object motion the pha...
متن کاملTechnique for the removal of speckle phase in electronic speckle interferometry.
It is shown that the speckle nature of electronic speckle pattern interferometry images can be reduced in quasireal time with the use of only three consecutive video images. By use of additive-subtractive phase modulation processing the technique is essentially insensitive to environmental noise, and distortion of fringes does not occur. By further removing the random speckle phase we show, usi...
