As　a　widely　used　lensless　coherent　diffraction　imaging　approach,　ptychography　has　recently　been　implemented　in　Terahertz　range.　Combining　with　the　unique　penetration　property　of　THz　radiation,　THz　ptychography　allows　inspecting　visually　opaque　samples　and　retrieving　both　amplitude　and　phase　information.　Here,　we　demonstrate　for　the　first　time　to　our　knowledge,　THz　ptychography　in　reflective　configuration.　Due　to　the　large　wavelength　(96.5　µm),　THz　ptychography　requires　small　recording　distance.　Particular　care　has　been　taken　in　the　experimental　setup　to　minimize　the　recording　distance.　Extended　ptychographic　iterative　engine　(ePIE)　is　applied　to　reconstruct　quantitatively　the　amplitude　and　phase　information　of　the　object　wavefront.　A　lateral　resolution　of　180　µm　and　a　depth　resolution　of　1.1µm　are　achieved.　©　COPYRIGHT　SPIE.
