Imaging through scattering media via spatial–temporal encoded pattern illumination

Optical imaging through scattering media is a long-standing challenge. Although many approaches have been developed to focus light or image objects media, they are either invasive, restricted stationary slowly-moving require high-resolution cameras and complex algorithms retrieve the images. Here we introduce computational technique that can overcome these restrictions by exploiting spatial-temporal encoded patterns (STEP). We present non-invasive with single-pixel photodetector. show method insensitive motions of media. further demonstrate our reconstruction algorithm much more efficient than correlation-based for imaging, which may allow fast in currently unreachable scenarios.
