WebDec 1, 2024 · In this paper, we propose a holographic magnification system based on a cylindrical lens. By using a combination of digital orthogonal cylindrical lenses on a SLM and a solid cylindrical lens, we can control vertical zoom in the holographic magnification system very quickly. WebIn the method, the pre-magnification recording geometry is realized by a cylindrical lens (CL) or cylindrical beam instead of a conventional objective or spherical beam in traditional off-axis digital holography (DH). At the same time, the reference beam is replaced by a divergent cylindrical beam.
