Abstract:
     It is a method to lessen diffraction angle in holography phase difference amplifying, which comprises the following steps: to put the holography amplified on workbench and shoot it with parallel He-Ne laser amplified; to optically amplify the holography by one image forming lens; to record the holography with fringe distance amplified with a holography plate and then to do dark developing, image fixation and dry and to put the holography to the co-axis phase difference amplifying device and to substitute original holography and to amplify the phase difference; to repeat the above steps to get holography with higher time.
