An improving method of imaging through scattering medium under strong background illumination

Imaging through scattering medium has long been one of the challenges in many fields. At present, many invasive and non-invasive methods have been proposed to image through scattering medium. However, these methods are only limited to the dark field scenario, which are very sensitive to the background illumination and leads to the failure of the reconstruction process. In this work, we proposed an improving method that enables imaging through scattering medium under strong background illumination. It consists of retrieving the target from the speckle patterns and removing the background illumination in the autocorrelation images. Our method can retrieve the feature and spatial information of the target from a single shot of the camera image without complicated phase-retrieval algorithm. In addition, our method also provides an efficient solution for scattering imaging of wide-spectrum targets, and the color information will be displayed in the multispectral image of the final result.
