High-Pressure Multi-Spectral Diagnostics
imaging in high-pressure environments are confronted by a
number of problematic issues. Broadening of excitation
lines, interference from alternative species, and
collisional quenching are just a few when using ultraviolet
laser light for diagnostics. This research addresses both
simulation and experimental approach of using multi-spectral
detection to enhance sensitivity and reliability of LIF
imaging at elevated pressures.
