Photoacoustic Soot Measurement System for Cleaner Engines

NIST Inventors
Amy Mensch , Ryan Falkenstein-Smith and Thomas Cleary
This invention introduces a photoacoustic measurement system that detects soot deposition in engines. It works by irradiating soot deposits with pulsed electromagnetic radiation, causing rapid expansion that generates an acoustic pressure wave. The system then senses the pressure wave using an
Diagram of the dual optical frequency comb spectrometer consisting of a single laser that is split into local oscillator, reference and probe legs to down-convert, interleave and normalize gas sample absorption signals.

Variable-Frequency Optical Combs, Heterodyne Sensor, and Process for Performing Spectroscopy

NIST Inventors
David F. Plusquellic , Kevin O Douglass , Joseph T. Hodges and Adam J. Fleisher
This invention uses lasers and modulators to create special light waves called “optical frequency combs” that can scan multiple chemical features instantly. These combs detect chemicals by analyzing how light changes as it interacts with different substances. It’s fast, accurate, and doesn’t need
TPOP optical probe.

A Probe for Rapid and Flexible Evaluation of Photonic Integrated Circuits (PICs)

NIST Inventors
Kartik Srinivasan
The Tapered Polymer Optical Probe (TPOP) is a state-of-the-art light probe that collects light from very small, localized areas. It is a small loop of a thin plastic "string" that collects light from a localized area near the loop into a fiber optic for signal testing. The probe is made of a durable
