Optical imaging/tracking through scattering medium is a difficult challenge. We demonstrate a method using speckles with multiple bit depths to image objects through scattering medium. The image of the object can be reconstructed even if the speckles are binary. Speckles with different bit depths are obtained by quantifying the original speckle. And we discuss the application of binarized speckles in tracking moving object. The binarized speckles can be used to recover the track with high accuracy. The range of the object's motion can be much larger than the range of memory effect, as long as the object's size and the moving step are within the range of memory effect. Imaging and tracking with low bit depth have the potential to reduce the hardware requirements of camera and storage space of images.

通过具有低位深散斑的散射介质成像和跟踪

通过散射介质进行光学成像/跟踪是一项艰巨的挑战。我们演示了一种使用具有多个位深度的散斑通过散射介质对对象进行成像的方法。即使散斑是二进制的，也可以重建物体的图像。通过对原始散斑进行量化得到不同位深的散斑。并讨论了二值化散斑在跟踪运动目标中的应用。二值化散斑可用于高精度恢复轨迹。物体运动的范围可以远大于记忆效应的范围，只要物体的大小和移动步长在记忆效应的范围内即可。低位深度成像和跟踪有可能降低相机的硬件要求和图像的存储空间。
