Lensless wide-field single-shot imaging through turbid media based on object-modulated speckles

The need to image objects through light-scattering materials is common in a range of applications. Different methods have been investigated to acquire the image of the objects when diffusers are presented. In this paper, we demonstrate the object reconstruction with single-shot imaging based on correlography principle and phase retrieval algorithm with coherent illumination. We prove the possibility of reconstructing positive and negative object in both transmission and reflection modes with collimated and scattered light. Formulas for calculating the size of the object from the reconstructed image are presented. We also prove that the object can be retrieved from a small section of the raw speckle image, a property similar to holography. These interesting features will open new doors for imaging applications to wider areas.
