In order to overcome the coherence-induced artifacts, the illumination heterogeneity as well as a limited dynamic range when using full-field technique, a solution employing a galvanometric beam-steering is proposed, demonstrating the possibility for

The knowledge of the main optical paths contributing to the signal within stratified structures is unknown and nonintuitive. However, it would deepen THz-probing possibilities and improve property extraction processes. In this work, an iterative algo

Full-field terahertz imaging suffers both from a limited contrast dynamic and from interference fringes, due to the source coherency. We propose a solution to both, homogeneously illuminate a selected area, and control the contrast dynamic and acquis
