用于光学层析成像的超声调制光是非常有用的，因为它可以以最小的数学处理提供三维数据。虽然几个实验研究已经显示了这种方法的潜力，超声定位和调制信号强度之间的联系在检测器尚未完全理解。我们推导出一个分析公式的超声换能器的位置和检测器处的光信号。我们还推导出作为换能器位置的函数的信号与散粒噪声比的表达式。我们表明，在某些条件下，这个比例只是缓慢地减少作为光的穿透深度的函数，这使得这种技术的光学层析成像的吸引力。
Ultrasound modulated light for optical tomography is very useful, since it can provide three-dimensional data with minimal mathematical processing. Although several experimental studies have shown the potential of this method, the link between the ultrasound location and the modulated signal intensity at the detector is not yet fully understood. We derive an analytical formula relating the position of the ultrasound transducer and the optical signal at the detector. We also derive an expression for the signal-to-shot-noise ratio as a function of the transducer position. We show that in certain conditions this ratio is only slowly decreasing as a function of the light penetration depth, which makes this technique attractive for optical tomography.
