Tera-sample per second real-time waveform digitizer

Tera-sample-per-second Real-time Waveform Digitizer

We demonstrate a real-time transient waveform digitizer with a record 1 TSa/s (TeraSample/sec) sampling rate. This is accomplished by using a photonic time stretch preprocessor which slows down the electrical waveform before it is captured by an electronic digitizer. * Present address: College of Optics and Photonics: CREOL & FPCE, University of Central Florida, 4000 Central Florida Blvd., Orla...

Electro-Optical DSP of Tera Operations per Second and Beyond (Extended Abstract)

We present a vector-by-matrix multiplier architecture incorporating the high potential of optical computing within electronics. This architecture stems from advances in optical switching technology, optical communication, and laser on silicon, and overcomes previous bottlenecks implied by the speed of transferring information to the optical vector-by-matrix multiplier. Based on this architectur...

Real-time volumetric lipid imaging in vivo by intravascular photoacoustics at 20 frames per second.

Lipid deposition can be assessed with combined intravascular photoacoustic/ultrasound (IVPA/US) imaging. To date, the clinical translation of IVPA/US imaging has been stalled by a low imaging speed and catheter complexity. In this paper, we demonstrate imaging of lipid targets in swine coronary arteries in vivo, at a clinically useful frame rate of 20 s-1. We confirmed image contrast for athero...
