电子全息成像由麻省理工学院媒体实验室的空间成像小组开发,是一种真正的 3D 实时数字成像介质。全息视频的最新进展表明,关键技术——计算、电子信号处理、光学调制和扫描——可以扩大规模以产生更大、更具交互性的全彩全息图像。通信瓶颈的克服依赖于使用新开发的“衍射特定”计算算法来生成编码全息图,并以大约二十比一的系数压缩。在这里,我们描述了使用为 Cheops 视频处理系统构建的流处理器硬件对全息图进行快速“解压缩”的进展。结果是,36 MB 全息图像可以在大约六秒内通过 SCSI 链路更新,接近真正的交互速度。
Electronic holographic imaging, as developed at the MIT Media Laboratory's Spatial Imaging Group, is a truly 3D real-time digital imaging medium. Recent progress in holographic video has demonstrated that the crucial technologies--computation, electronic signal manipulation, and optical modulation and scanning--may be scaled up to produce larger, more interactive, full-color holographic images. The overcoming of communication bottlenecks relies on the use of newly-developed 'diffraction-specific' computational algorithms to produce encoded holograms that are compressed by factors of about twenty to one. Here we describe progress in the very rapid 'decompression' of the holograms with stream-processor hardware built for the Cheops video processing system. The result is that 36-MB holographic images may be updated over a SCSI link in about six seconds, approaching truly interactive speed.
