Paper Abstract

We report here progress on a NASA program to develop fiber optic interferometric sensors for aeroacoustic measurements. As reported earlier, NASA's first fiber-optic microphone was developed and fabricated. Preliminary anechoic chamber tests demonstrated successfully its feasibility as an aeroacoustic sensor. Improved performance of a newly designed sensor head is presented here in terms of frequency response function and noise floor.
