High speed switching between arbitrary spatial light profiles.
Complex images, inscribed into the spatial profile of a laser beam or even a single photon, offer a highly efficient method of data encoding. Here we present a prototype system which can quickly modulate between arbitrary images. We display an array of holograms, each defined by its phase and intensity profile, on a spatial light modulator. The input beam is then steered by an acousto-optic mod...
متن کاملHigh-speed Multi-level 512x512 Spatial Light Modulator
Recent advancements in our high-speed multi-level (analog) 512x512 liquid crystal Spatial Light Modulator (SLM) will be presented. These advancements include smaller pixel pitch, greatly improved optical efficiency, and higher speed operation. The new VLSI SLM can utilize Ferroelectric Liquid Crystal (FLC) or Nematic Liquid Crystal (NLC) to achieve phase-only, amplitude-only, and phase-amplitud...
متن کاملHigh-speed spatial frequency domain imaging with temporally modulated light.
Spatial frequency domain imaging (SFDI) is a wide-field diffuse optical technique used to obtain optical properties and chromophore concentrations in highly scattering media, such as biological tissue. Here, we present a method for rapidly acquiring multispectral SFDI data by modulating each illumination wavelength at a different temporal frequency. In the remitted signal, each wavelength is te...
متن کاملIsochronets: A High-Speed Network Switching Architecture
Traditional switching techniques need hundredor thousand-MIPS processing power within switches to support Gbit/s transmission rates available today. These techniques anchor their decision-making on control information within transmitted frames and thus must resolve routes at the speed in which frames are being pumped into switches. Isochronets can potentially switch at any transmission rate by ...
متن کاملHigh-speed parallel external sorting of data with arbitrary distribution
Many parallel sorting algorithms of (external) disk data have been reported such as NOWsort, SPsort, and hill sort, etc. They all reduce the execution time compared to some known sequential sort; however, they differ in terms of the speed, throughput, and cost-effectiveness. Mostly they deal with data that are uniformly distributed in their value range. If we divide and redistribute data to pro...
