The invention relates to a liquid lens based color holographic zoom system, which aims to solve a technical problem that the existing holographic 3D zoom system is complex in structure, difficult to operate and poor in quality of a reproduced image. The technical scheme adopted by the invention is that the liquid lens based color holographic zoom system comprises a three-color light source, a beam splitting prism, a spatial light modulator, a computer, a liquid lens, a receiving screen and a synchronization control circuit; the three-color light source is arranged on an incident light path of the beam splitting prism, the spatial light modulator is arranged on a reflection light path of the beam splitting prism, the liquid lens is arranged behind the spatial light modulator, and the receiving screen is arranged behind the liquid lens; the three-color light source passes by the beam splitting prism and then irradiates on the spatial light modulator, and the light source modulated by the spatial light modulator is projected to the receiving screen after being zoomed by the liquid lens; and the synchronization control circuit ensures the switching time of the light source, a hologram and the liquid lens to be consistent.
Description
technical field [0001] The invention relates to a liquid lens-based color holographic zoom system, which belongs to the technical field of holographic display. Background technique [0002] Three-dimensional (3D) display Since the 1980s, there have been various methods such as glasses-type 3D display, multi-viewpoint 3D display, and holographic 3D display. Among them, holographic 3D display can completely record and reconstruct the wavefront of 3D objects, and provide all the depth information required by the human visual system, so it is widely regarded as the ultimate goal of 3D display in the world. In order to adjust the size of the reproduced image, the traditional method is to change the position of the reproduced image by mechanically moving the position of the lens or the relative position between the lens groups, thereby changing the size of the reproduced image. Systems for this approach are usually complex and difficult to operate, and the system will be even mor...
