Rapid Scanning Near-Infrared/Infrared Spectrometer
Title: Principal Investigator

This project involves a feasibility study for a rapid scanning near-infrared/infrared spectrometer for transient, simultaneous measurements of CO2 and H20 concentrations, soot volume fractions and temperatures. Such measurements can lead to improved understanding of the structure of turbulent and laminar flames. A commercial instrument that can reliably provide simultaneous gas concentrtaion, soot volume fraction and temperature measurements is not available.
The Phase II work will involve use of an infrared focal plane array detector along with a dispersion grating to obtain time resolved measurements of spectral radiation intensity (9 nm resolution) from 2295 nm to 4585 nm. A thermoelectric cooled lead selenide array detector will be used in conjunction with an interactive algorithm to obtain the transient gas species concentrations, soot volume fractions and temperatures within a flame. The Phase I work will focus on evaluating the technical feasibility of obtaining such information using the proposed near infrared/infrared spectrometer.
