Publisher: IEEE Yucheng Li; Yang Zhang Abstract: This article first analyzes the two-step imaging process in optical holography, namely wavefront recording and wavefront reconstruction. According to the relationship of the four diffraction components in the spatial spectrum of the off-axis digital holography diffraction process, the minimum angle is derived between the object light and the reference light of the off-axis digital holography. According to the sampling theorem, the maximum angle is derived between the object light and the reference light in off-axis digital holography. The mathematical derivation of holography algorithm is introduced based on these foundations. In the experiment, a light path system was used to study the method of eliminating zero order in off-axis digital holograms by recording reference light at different angles to the X-axis or Y-axis, while improving the image resolution of off-axis digital holographic reconstruction. |
