碩士 === 國立中央大學 === 光電科學與工程學系 === 102 === In this thesis, we propose a new method that using light pipe to extend space-bandwidth product by increasing field of view and the resolution at the same field of view simultaneously. One of the applications is to use light pipe to replace the objective lens for miniaturize the microscope with digital holography. On the other hand, this method can be used to extend effective CCD pixel number so that it is helpful to storage capacity and access rate. We propose to use light pipe between object and image detector. It can enhance resolution of reconstructed image by using reflective surface to collect signal light in high frequency. We also use mirror image to overcome space-bandwidth limit, and establish a computing method to reconstruct image in different object lights or reference light. Finally, the corresponding experiments are done, and image resolution and field of view are improved, respectively.
