Abstract

Imaging objects hidden behind opaque layers is significant in many fields, with applications ranging from biomedical imaging to defense security. Techniques based on memory-effect scattering imaging have been developed in the past decade. The existing memory-effect-based scattering imaging techniques can be divided into two categories based on the working principle of light sources. In these methods, phase-retrieval algorithm is used to reconstruct object from the power spectrum diffraction patterns as the last step. Although both of them achieve single-shot scattering imaging, the experimental set-up is quite different. It is noted that the coherent diffraction imaging is introduced to the scattering imaging field using the visible coherent light. The principle and setup of the aforementioned two methods are analyzed and summarized respectively. We experimentally demonstrate the reconstruction and evaluate the Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Image Measurement (SSIM). As these technologies are limited to short range and memory effect range, the potential to imaging with wide field of view and long distance requires further exploration.
