Abstract
Shadow Scanning Lens-free Microscopy (SSLM) is a possible method for optical imaging that can potentially achieve high spatial resolution. At present work we discuss the SSLM and analyse the resolution limit conditioned by the light scattering from the edge scanning imaging system that uses a shadow from moving knife edge or wire to collect the sets of tomographic projection data of two-dimensional objects. The results of numerical estimation of the SSLM resolution for reconstruction of 2D object image are presented. The experimental setup of SSLM with wire scanning element was developed. The developed device works in a UV band range and shows the spatial resolution about 90 nm.
