提供了全场2D振幅和相位振动分析的机会。它表明，它是可能的，同时编码-解码2D的振幅和相位的谐波机械振动。当物体处于纯正弦激励下时，该过程允许确定平面内和平面外的振动分量。其原理是基于数字菲涅耳全息术中的空间复用。实验结果的情况下，工业应用。
Opportunities for full field 2D amplitude and phase vibration analysis are presented. It is demonstrated that it is possible to simultaneously encode-decode 2D the amplitude and phase of harmonic mechanical vibrations. The process allows the determination of in plane and out of plane vibration components when the object is under a pure sinusoidal excitation. The principle is based on spatial multiplexing in digital Fresnel holography. Experimental results are presented in the case of an industrial application.
