| Outline of Final Research Achievements |
The generalized phase-shifting method has been proposed. Arbitrary phase-shifting quantities not restricted to a multiple of π/2 can be used. The method does not use polarimetric information. Therefore not only complex-amplitude but also spectroscopic information or polarimetric information can be obtained by the method.
In this research, the constrains on the reference wave is confirmed in terms of its spatial frequency. The optical experiments shows the suitable characteristics of the reference wave by its spatial frequency distribution and the reconstructed images.
For the spectroscopic imaging, the experiment using a transparent object consisting of color cellophane papers as an object confirmed the proposed method. For the polarimetric imaging, a method using generalized phase-shifting method was not succeeded. However, the idea of the polarimetric imaging, Mueller matrix imaging for a quarter wave plate was shown by the optical experiment.
