PHOTOACOUSTIC PHOTON METER AND PROCESS FOR MEASURING PHOTON FLUENCE

NIST Inventors
Kimberly A. Briggman , Chris Yung , Jeeseong C. Hwang and John H. Lehman
patent description This invention pertains a concept of a carbon nanotube (CNT)-based integrated sensor which can measure spatial and spectral photon fluence (energy per unit area or volume in the spatial or spectral domain), temperature, and pressure in turbid media and can evaluate performance of

Optical Phantom for Producing a Time-Resolved Diffuse Reflectance Spectrum

NIST Inventors
Jeeseong C. Hwang
Patent Description Physikalisch-Technische Bundesanstalt (PTB) and NIST jointly developed a concept for a waveform synthesizer which can generate a controlled waveform with several picosecond (ps) time resolution. In a light-diffusing material, characteristics of the time-of-flight distribution (e.g
X-Ray Spectrometer

X-Ray Spectrometer

NIST Inventors
Kevin L. Silverman , Carl D. Reintsema , Galen O'Neil , Luis Miaja Avila , Daniel Swetz , W.Bertrand (Randy) Doriese , Dan Schmidt , Bradley Alpert , Joseph Fowler , Joel Ullom , Ralph Jimenez and Gene C. Hilton
Patent Description Presently, there are no commercial tools for x-ray absorption and emission spectroscopy with picosecond time resolution. Additionally, there are no tabletop tools for x-ray emission spectroscopy with picosecond time resolution. Previously, x-ray emission spectroscopy with this
Step-by-step process for making a self-aligned waveguide

Process for Making a Self-Aligned Waveguide

Patent Description This invention enables practitioners to achieve very narrow gaps, down to 0.1 µm, on long coplanar waveguides using optical lithography. This process is shown below. In step 1, a mask is defined on top of the metallic material to be used as the center trace of the coplanar

Multiple Output-tap Josephson Voltage Standard

NIST Inventors
Samuel P. Benz , Paul Dresselhaus , Alain Rufenacht , Nathan Flowers-Jacobs and Anna Fox
patent description The invention is a method for producing multiple voltage outputs simultaneously with single or multiple Josephson voltage circuits implemented in a single cryogenic system. The output voltages can be of fixed ratio, independently programmable, or frequency/phase locked for ac

TEMPORAL JITTER ANALYZER AND ANALYZING TEMPORAL JITTER

NIST Inventors
Joshua Bienfang
patent description The invention is a method to characterize the temporal variation, or “jitter,” of a single-photon detector’s response with high accuracy. The method addresses the need to characterize single-photon detectors whose jitter is in the few-picosecond range. The method works as follows
