Application of Supercontinuum Generation to Practical Absorption Spectroscopy
Abstract
Supercontinuum light generation was used as a means to generate broadband light
for spectroscopic measurements. The generated broadband light was used to
measure carbon monoxide (CO) absorption in a sealed laboratory test cell. This
investigation served as a proof of concept for optical system development that in the
future can be applied towards making combustion measurements.
Some of the basic concepts underlying supercontinuum generation are reviewed
and the advantages and disadvantages of this broadband light generation technique
are discussed. Particularly, interference brought on by the propagation of
broadband light is reviewed and methods to deal with it are discussed. The
distinction between high and low quality light for making spectroscopic
measurements is detailed and CO absorption measurements were made using both
types of light. From reviewing the results, it was found that high quality light is
superior to low quality light for making high-speed spectroscopic measurements.
