    摘要: A device for analyzing a material, the device having a photo acoustic generator (40) for generating pressure waves in the material by pulsed illumination by a light source, and a sensor (20, 30, 50) for producing a signal using self mixing interferometry, the signal representing displacements of the material due to the pressure waves, and a signal processor (60) for processing the signal to analyze the material. This combination of photo acoustic stimulation and self mixing interferometry sensing helps reduce or avoid errors or distortions caused by sensor contact on the material, and can provide a better ratio of sensitivity for a given degree of compactness of the device.
