Abstract
Apparatus, methods, and other embodiments associated with monitoring combustion dynamics in a gas turbine engine environment are described herein. In one embodiment of a system for monitoring combustion dynamics in a gas turbine engine environment, the system includes a transducer and an optical fiber. The transducer is positioned within the gas turbine engine environment, and the transducer includes a diaphragm, a window, and a Fabry-Perot gap. The diaphragm has a reflective surface, and the window has a partially reflective surface. The Fabry-Perot gap is formed between the reflective surface of the diaphragm and the partially reflective surface of the window. The optical fiber is positioned proximate to the window and directs light into the Fabry-Perot gap and receiving light reflected from the Fabry-Perot gap.
