Abstract:
Method and device for detecting and analyzing movement in a scattering medium, by: projecting a coherent light towards the scattering medium; performing a spatial and temporal sampling of the electromagnetic field of scattered light, in order to obtain a plurality of images of the electromagnetic field; and analyzing the speckle grains resulting from the images obtained from the spatial and temporal sampling of the electromagnetic field of the scattered light, in order to detect and analyze a movement in the scattering medium, the speckle grain analysis step including a step of analyzing the inter-image distance.
