Focus on sub-nanometer measurement accuracy: distortion and reconstruction of dynamic displacement in a fiber-optic microprobe sensor

We established a complete model and relationship between laser source characteristics and measurement accuracy of high precision fiber microprobe sensor (FMS) based on phase generated carrier demodulation. The laser carried out high-bandwidth frequency modulation to improve the measurement speed. Me...
