摘要：
The tuning behaviour of widely tunable (> 500 GHz) laser diodes for high modulation frequencies and the resulting systematic error for short-distance measurements with a frequency-modulated continuous wave (FMCW) lidar (light detection and ranging) utilizing a reference interferometer is calculated. The results show that the nonlinear tuning characteristic has to be corrected for high-speed applications.
