摘要：

Terahertz　(THz)-wave　in-line　digital　holography　imaging　is　a　new　imaging　technique　based　on　interferometry　record　of　terahertz　wave.　It　exhibits　advantages　for　the　THz　imaging　because　it　only　needs　low　coherence　light　source　a　simple　optical　structure,　and　has　high　resolution　imaging　and　access　to　quantitative　real-time　complex　complitude　of　light　wave.　We　built　a　continuous-wave　THz　in-line　digital　holographic　setup.　By　preprocessing　hologram　and　phase　recovery　algorithm,　we　obtain　amplitude　and　phase　contrast　images　of　the　sample　and　effectively　inhibit　the　conjugate　image.　Further,　the　feasibility　of　THz　in-line　digital　holography　is　explored　in　biomedical　detection.
