Non-invasive tracking of moving objects behind scattering layers from a single multiplexed speckle

Abstract With the development of the techniques for imaging through scattering layers, the speckle multiplexing methods have been applied in many fields. Based on this, we present a method for non-invasive imaging and tracking of moving and changing objects hidden behind scattering layers from a single multiplexed speckle (SMS). The speckles from the moving objects are detected at different moments, which are numerically rotated with predesigned angles and multiplexed in a SMS afterwards. To recover the object image and position at each moment, the SMS is demultiplexed by calculating the cross-correlation between the SMS before and after numerical rotation. Then, the non-invasive imaging and tracking of the moving object from the SMS is realized. For changing or rotating objects, the object images can also be reconstructed with accurate motion trails with the combination of a de-correlation algorithm. This simple method is helpful for applications in single-shot video, multiple-image encryption, etc.
