摘要
介绍了在超快液晶薄膜中的实时动态全息视频显示成果,此薄膜不需任何外加电场,而且全息响应在毫秒量级,全息图建立和自擦除时间最快都可达到1ms。利用红绿蓝(RGB)三色激光作为读出光获得了无串扰噪声红绿蓝三色实时动态全息显示视频。基于全息复用技术,在此材料中实现RGB模式彩色全息视频显示。由于此材料易于制成大尺寸显示屏,而且无需任何外加电场,所以由其制成的空间光调制器或其他全息显示器件无需进行像素化,这样就能有效地克服现有空间光调制器的缺陷,其有望在未来被开发成高分辨率、大尺寸、彩色实时动态全息三维视频显示器。
Real-time dynamic holographic video display is presented in a super fast liquid crystal thin film with holographic response in the order of a millisecond and without any applied electric field. Both the formation time and self-erasure time of holographic images are 1 ms. Real-time dynamic holographic videos are achieved at red, green and blue laser without cross talk between the holograms. Furthermore, color holographic display in RGB model is realized by holographic multiplexing. Because the sample is easy to be made into a large size screen and needs no external electric field, any spatial light modulators or other holographic display devices resulting from this material will not be pixilated, and it can conquer the defect of existing spatial light modulator. It is believed that the film can be developed into a high resolution, large-size, real-time dynamic, and color holographic three-dimensional display in the future.
