摘要:
设计并搭建基于光纤和偏振图像融合的无透镜傅里叶变换数字全息实验装置,利用电荷耦合元件(CCD)记录物光波振幅、相位及偏振信息,完成偏振图像融合和数字全息再现.实验结果表明:结合偏振图像融合技术的无透镜傅里叶变换数字全息能得到更为准确的数字全息图和再现像;基于光纤的无透镜傅里叶变换数字全息不仅能产生近似球面波,而且使物体到CCD的位置更自由.此外,偏振图像融合的方法和中值滤波器的使用,能有效地提高再现像的分辨率.
Abstract:
The experimental setup of lensless Fourier transform digital holography(LFDH)based on optical fiber and polarization image fusion is designed and presented. The phase, amplitude and polarization information of object light can be recorded by charge-coupled device(CCD), and the reconstruction of digital holography and the polarization image fusion can be realized availably. The experimental result shows that LFDH combined with polarization image fusion technology can obtained more accurate reconstruction image. By using optical fiber of high numerical aperture, not only approximate spherical wave can be acquired but also the position of object in LFDH is more free. Furthermore, polarization image fusion and median filtering algorithm are successfully used to improve the resolution of the reconstruction image.
