Fiber sensing application incl. environmental monitoring using optical network

Digital pre-distortion method based on jointly least-square fitting and endpoint fitting is proposed to correct frequency nonlinearity for FMCW LiDAR system with 100 kHz tuning rate, which can reduce the relative residual nonlinearity to 0.026%.
