Figure 2. Acousto-optic modulation (AOM) intensity and modulation depth increase linearly with squared ultrasound pressure.

Figure 2

For incoherent light traveling through an ultrasound focal zone, the AOM intensity (top) and modulation depth (bottom) are linearly proportional to the squared ultrasound pressure within the focal zone.
