abstract = {This work reports the analysis of a single lens fiber optical microphone configuration. The proposed microphone is basically constituted by only two optical fibers, a single lens, a reflective membrane, a laser, and a photodetector. A theoretical analysis was conducted to determine the main modulation parameter of the microphone. The system was able to detect sound waves up to 6 kHz with a dynamic range of 50 dB, and it was compared with more complex optical microphones. Such configuration is simple and low cost with potential for voice communication and sensor application. Index Terms Fiber communication, optical sensor.},
