This is an invited predictive paper, written in part as a response to a predictive paper published in 1962 and in part as a prediction of technology and life in 2048. Overview of electro-holography. This diffraction-specific approach, treats a fringe as discretized in space and spatial frequency.
Analysis focuses on the trade-offs among compression ratio, image fidelity, and image depth.
A novel electro-holographic bandwidth compression technique, fringelet bandwidth compression, is described and implemented. Fringelet decoding is extremely simple, enabling an overall increase in fringe computation speed of over 3000 times compared to conventional interference-based methods. We used this method to render holograms on a conventional computer graphics workstation. MIT Dept. of Electrical Engineering and Computer Science , Sept. 1994. A new, fast, versatile method of holographic fringe computation is described, implemented, and analyzed.
