声光 (AO) 成像是一种很有前途的技术，它能够通过用超声波束标记光子路径来揭示散射介质内毫米范围内的光学特性。为了提高 AO 图像的对比度和分辨率，我们探索了使用散斑调制的非线性响应的可能性。已经发现二次谐波信号随着超声波幅度的平方而变化，并且已经证明了标记区域尺寸的大幅减小。
Acousto-optic (AO) imaging is a promising technique that is able to reveal optical properties in the millimeter range inside scattering media by tagging the photon paths with an ultrasonic beam. To increase both the contrast and the resolution of the AO images, we have explored the possibility of using the nonlinear response of the speckle modulation. Variation of the second-harmonic signal as the square of the ultrasonic amplitude has been found, and strong reduction of the tagged zone size has been demonstrated.
