Frequency Resampling Enabled Fast Pre-Distortion Linearization of Laser Frequency Sweeping
Abstract
A fast and low-cost pre-distortion linearization algorithm for laser frequency sweeping calibration is highly desired for frequency-modulated continuous wave (FMCW) lidar applications. We propose a frequency resampling-based pre-distortion strategy, which enables the laser sweeping residual nonlinearity to reach 10-8level with only 8 or less iterations and does not require any additional hardware compared to external modulation or optical phase locked loop methods.
