与电荷耦合器件相机连接的超声波调制光学散斑测量已被开发出来，用于研究通过同轴传输系统中的强散射介质传播的脉冲超声波调制的生物散斑图案行为。该方法以亚毫米空间分辨率揭示了位于 10.0 毫米厚的阻抗匹配散射介质内 5.0 毫米深度的吸收物体。通过在散斑图案中引入定量值来评估调制图案，我们成功获得了一系列吸收分布值，同时将信噪比提高了3.8倍。
Ultrasound-modulated optical speckle measurement interfaced with a charge-coupled device camera has been developed to study the biological speckle pattern behavior modulated by a pulsed-ultrasound wave propagating through strong scattering media in a coaxial transmission system. This method reveals an absorptive object located at 5.0 mm depth within a 10.0 millimeter thick impedance-matched scattering media with submillimeter spatial resolution. Introducing a quantitative value to the speckle pattern in order to evaluate the modulated patterns, we have succeeded in obtaining a series of absorptive distribution values, and simultaneously have improved the signal to noise ratio by 3.8 times.
