In this work, a highly sensitive vernier sensor based on Chirp Grating Fabry-Perot Interferometers (CG-FPI) is experimentally demonstrated for the detection of small strain signal in Lithium Polymer (LiPo) battery. The vernier sensor is assembled from two CG-FPIs with small difference in free-spectr...
