Holographic magnification system based on cylindrical lens

In this paper, we propose a holographic magnification system based on a cylindrical lens. The cylindrical lens has the function of converge and diverge beam only in the sagittal direction. The digital cylindrical lens consists of digital orthogonal cylindrical lenses on a spatial light modulator (SLM) and a solid cylindrical lens, and the vertical zoom in the holographic magnification system can quickly be controlled. The vertical magnification can be adjusted by tuning the focal length of the two digital cylindrical lenses. In order to illustrate the capabilities of the system, some experimental results are given.
