Schematic of double-beam modulation spectrometry using a single detector

Single-Detector Double-Path Intensity-Modulation Spectrometer

NIST Inventors
Young Jong Lee
This invention is an optical method that can minimize the noise due to system fluctuations and maximize the signal-to-noise ratio by modulating the analyte beam and the reference beam and detecting the alternating intensity difference by a signal light detector. This invention is based on a double
Schematic comparison of the conventional approach and this invention for a sample (analyte + solvent) with a strong solvent absorption band in the spectral range of interest.

Spectrum Adjuster and Producing a Pure Analyte Spectrum

NIST Inventors
Young Jong Lee
A spectrum adjuster produces a pure analyte spectrum and includes: a dynamic opacity optic that receives input light, receives an adjustment signal, produces primary adjusted light, and produces secondary adjusted light from the input light based on the adjustment signal; a light source in optical

3D Printing of Composition-Controlled Copolymers

NIST Inventors
Young Jong Lee
A computer-controlled method for forming a composition-controlled product using 3D printing includes disposing two or more liquid reactant compositions in respective two or more reservoirs; and mixing the two or more liquid reactant compositions, which in turn includes controlling by the computer a
