Holographic bandwidth compression using spatial subsampling
Subject terms: electro-holography, holographic computation, holographic bandwidth compression, diffractionspecific, fringelet, hogel vector Abstract. A novel electro-holographic bandwidth compression technique, fringelet bandwidth compression, is described and implemented. This technique uses spatial subsampling to reduce the bandwidth and complexity of holographic fringe computation for real-t...
متن کاملImproving cross-validated bandwidth selection using subsampling-extrapolation techniques
Cross-validation methodologies have been widely used as a means of selecting tuning parameters in nonparametric statistical problems. In this paper we focus on a newmethod for improving the reliability of cross-validation. We implement this method in the context of the kernel density estimator, where one needs to select the bandwidth parameter so as to minimize L2 risk. This method is a two-sta...
متن کاملSubsampling-based compression and flow visualization
As computational capabilities increasingly outpace disk speeds on leading supercomputers, scientists will, in turn, be increasingly unable to save their simulation data at its native resolution. One solution to this problem is to compress these data sets as they are generated and visualize the compressed results afterwards. We explore this approach, specifically subsampling velocity data and th...
متن کاملBandwidth compression optical processor using chirped fiber Bragg gratings
Chirped fiber Bragg gratings are used as low-loss, dispersion compensation modules for telecommunications applications. Here we use them to make an optical processor that compresses the bandwidth of electronic signals before digitization by an analog-to-digital converter. ©2007 Optical Society of America OCIS codes: (230.0250) Optoelectronics, (060.2360) Fiber optics and optical communications ...
متن کاملThree-dimensional parallel holographic micropatterning using a spatial light modulator.
We present a micropatterning method for the automatic transfer and arbitrary positioning of computer-generated three-dimensional structures within a substrate. The Gerchberg-Saxton algorithm and an electrically addressed spatial light modulator (SLM) are used to create and display phase holograms, respectively. A holographic approach to light manipulation enables arbitrary and efficient paralle...
