Simulation experimental research on controllable magnification reconstruction of Fresnel holographic reconstructed images

Fresnel digital holography can quickly perform three-dimensional imaging of objects, but due to the pixel size limitation of the image sensor CCD (Charge Coupled Device), its reconstructed image is smaller than traditional optical holographic imaging, which limits the adaptability of Fresnel technology to large-scale imaging. Therefore, expanding the pixel occupancy rate of Fresnel reconstructed images is particularly important. This paper is based on the analysis of the recording and reproduction principles of the Fresnel system, which designs a Matlab simulation experiment with controllable reproduction image magnification. And the reliability of this research method is verified through numerical simulation, and the best reproduction image magnification M is found.
