Magnification Rate in 3D Optical Scanning Holography Recording

Optical scanning holography (OSH) is a powerful holographic recording technique that employs a single-pixel photo-detector and 2D scanning mechanism to capture the hologram of a wide-view and 3D object. However, in OSH experiments, we found that 2D

scanning mirrors would cause unavoidable magnification and lateral resolution issues in 3D recording or sectioning imaging. In this letter, we will discuss this problem both theoretically and experimentally. The experiment results show that our results have a good performance on these issues.
