Outline of Final Research Achievements |
In line holography has a problem on low accuracy in the depth direction. We resolved this problem by using two sets of in line holography. As a result, we can observe the influence of a solid particle on vortex core by using the stereo in line holography. Additionally, we proposed the novel phase retrieval method for resolving twin image problem.
