Abstract

This paper presents a novel Non-Line-of-Sight (NLoS) imaging technique called Synthetic Wavelength Holography (SWH) that overcomes the limitations of scattering media by exploiting spectral correlations in scattered wavefronts. SWH achieves sub-mm resolution and a nearly hemispheric field of view, capturing the complete object field within 46ms using a small probe area. This combination of attributes opens up numerous applications in various fields.
