Abstract:
A method for improving acousto-optic activity for acoustic imaging, the method comprising:choosing a first medium, the first medium being chosen to have a first acousto-optic activity which causes a first optical property of the first medium to change with changes in acoustic energy intensity interacting with the first medium; choosing a second medium; adding the second medium to the first medium to form a net medium, the net medium having a net acousto-optic activity which causes a net optical property of the net medium to change with changes in acoustic energy intensity interacting with the net medium; substantiating that the net acousto-optic activity is greater than the first acousto-optic activity, by: determining a first optimum angle for imaging the first medium; determining a net optimum angle for imaging the net medium; choosing a value of a viewing baseline; comparing a first acousto-optic threshold of the first medium with a second acousto-optic threshold of the net medium, where the first acousto-optic threshold is measured at the first optimum angle and from the value of viewing baseline, and where the net acousto-optic threshold is measured at the net optimum angle and from the value of viewing baseline.
