An optical apparatus is disclosed. The optical apparatus includes an optical scanning module and a rotation axis module. The optical scanning module is used to provide an optical signal for optical tomography. The rotation axis module and the optical scanning module are integrated. When the rotation axis module rotates, the rotation axis module makes the optical scanning module to perform a rotation scanning process to an object.本發明揭露一種光學裝置。光學裝置包含光學掃瞄模組及旋轉軸模組。光學掃瞄模組係用以提供光學斷層掃瞄之光學訊號。旋轉軸模組係與光學掃瞄模組組合。當旋轉軸模組旋轉時,旋轉軸模組帶動光學掃瞄模組對待測物體進行旋轉掃瞄程序。30...光學掃瞄模組(光學探頭)32...旋轉軸模組3...光學裝置34...旋轉鏡36...操作平台38...判斷模組K...待測物體
