Acousto-optic imaging in liquids : a step towards in-vivo measurements

摘要

The aim of this paper is to show that we can perform acousto-optical signal acquisition of one datapoint (or voxel of a 3D image) in a very short time (2-4 ms), in order to overcome the speckle decorrelation effect. To demonstrate this, we have performed experiments in in dynamic scattering media such as liquids. We will show that we can work with pulsed wave ultrasound, to reduce the sound irradiation duration in order to be compatible with safety limits. These are significant steps towards in-vivo experiments.
