“Acoustic waves spectrally modulate supercontinuum light inside an acousto-optic tunable filter. The supercontinuum light interacts with resonating acoustic modes to produce four-lobed orange, green and rainbow Schaefer-Bergmann diffraction patterns around the two spectrally modulated beams and undiffracted light. These optical patterns can quantitatively measure acoustic properties of crystals.”
