【摘要】 实验研究了不同结构的多模光纤束斑纹场的单缝、双缝、三缝衍射花样及锲形空气薄膜干涉条纹。用 Y型多模光纤束拍摄了斑纹场全息光栅 ,研究了它的衍射花样。成功地用多模光纤束传光 ,测量散射物体的面内位移更多还原

【Abstract】 By means of experiments we study that,speckle fields emitted multimode fiber-optic bundle(MFOB) of different structure diffract pass through sing slit,bi-slit,three-slit,and thin film interference.By Y-mode MFOB take photograph of speckle holographic grating and study its diffraction pattern.We measured the displacement of scattering object in MFOB to propagate light with success.更多还原
