A fiber-type image capture apparatus includes a fiber, an optical rotating module, an outer tube, an air inlet hole, and an air outlet hole. The optical rotating module is disposed at one end of the fiber. The outer tube fixes the fiber and the optical rotating module. The air inlet hole and the air outlet hole are disposed at the outer tube. The optical rotating module includes a light path selector disposed at a rotor which includes a fan blade. Through inputting light with different predetermined wavelength bands, the user can choose a forward scanning path or a lateral scanning path, or both a forward scanning path and a lateral scanning path simultaneously by the light path selector. And, by feeding air to the fan blade, the rotor and the light path selector will rotate, and proceed the forward and lateral scanning. Then, the image capturing will be fulfilled by collecting the scattering light from the sample.一種光纖式穿透影像擷取方法及其裝置,包含一光纖、一光學旋轉模組、一外管、一進氣口及一出氣口,其中光學旋轉模組位於光纖之一端,外管包覆或固定光纖及光學旋轉模組,進氣口及出氣口位於外管。光學旋轉模組包含一光路選擇器安裝於一轉子,轉子具一扇葉。透過輸入不同預設波段的光線,於光路選擇器進行前向掃描路徑或側向掃描路徑,或同時進行前向及側向掃描路徑;再以進氣口對扇葉送氣使轉子帶動光路選擇器及其前向與側向掃描路徑旋轉,收集照射至待測樣品之散射光,可完成對待測樣品所進行的前向及側向影像之掃描及擷取。100‧‧‧單模光纖110‧‧‧光線入射軸向200‧‧‧光纖套管300‧‧‧聚焦光學模組400‧‧‧光學旋轉模組410‧‧‧光前出部420‧‧‧光側出部430‧‧‧光路選擇器平板440‧‧‧轉子450‧‧‧定子460‧‧‧固定軸471、472‧‧‧磁極500‧‧‧前向掃描路徑600‧‧‧側向掃描路徑700‧‧‧外管710‧‧‧進氣管720、750‧‧‧出氣管730‧‧‧固定結構800‧‧‧線圈組810‧‧‧線圈導線θ2‧‧‧傾斜角度D‧‧‧位移量L1、L2‧‧‧光源光線的波段R‧‧‧前向掃描路徑的半徑
