We demonstrate a technique, named dual structured laser illumination planar imaging (SLIPI), capable of acquiring depth-resolved images of the extinction coefficient. This is achieved by first suppressing the multiply scattered light intensity and then measuring the intensity reduction caused by signal attenuation between two laser sheets separated by Δz mm. Unlike other methods also able to measure this quantity, the presented approach is based solely on side-scattering detection. The main advantages of dual SLIPI is that it accounts for multiple scattering, provides two-dimensional information, and can be applied on inhomogeneous media.
我们展示了一种名为双结构激光照明平面成像（SLIPI）的技术，能够获取消光系数的深度分辨图像。这是通过首先抑制多次散射光强度，然后测量两个激光片之间因信号衰减而导致的强度降低来实现的，这两个激光片之间的距离为 Δz 毫米。与其他能够测量此数量的方法不同，所提出的方法仅基于侧向散射检测。双 SLIPI 的主要优点是它考虑了多次散射，提供了二维信息，并且可以应用于不均匀介质。
