The present invention relates to a medical laser with deep skin imaging system and method thereof. The system includes a self-interference module, a light module, a spatial filter module, a beam splitter module, an image sensing module and a laser module, wherein the self-interference module includes a focusing lens, a reference plate mirror and a self-interference objective lens. The FF-OCT of the system is that the self-interference objective lens is integrated with the focusing lens and the reference plate mirror in order to achieve interference function generated by a reference arm of a traditional FF-OCT. Therefore, the reference arm can be omitted. And then, the improved FF-OCT can be integrated into the medical laser system to improve its imaging and monitoring performance in operation of medical laser system.本發明係提供一種用於醫療雷射中的深層皮膚造影系統及其方法,其系統包含自干涉模組、光源模組、空間濾波模組、分光模組、影像感測模組以及雷射模組,其中自干涉模組包含聚焦透鏡、參考平面鏡以及自干涉物鏡,其系統之FF-OCT係將自干涉物鏡與聚焦透鏡以及參考平面鏡整合在一起,以實現傳統FF-OCT中的參考臂產生的干涉功能,因此可省略參考臂,並可將改良後的FF-OCT整合入醫療雷射系統中,以提升醫療雷射系統運作時的成像及監測性能。1000‧‧‧醫療雷射系統100‧‧‧雷射模組200‧‧‧光源模組300‧‧‧空間濾波模組310‧‧‧顯微透鏡320‧‧‧針孔330‧‧‧擴束鏡400‧‧‧分光模組500‧‧‧自干涉模組600‧‧‧影像感測模組2000‧‧‧待測物
