3D imaging sensors have applications that span several industries and markets, from industry metrology, robotic control to autonomous vehicles. Frequency-modulated continuous-wave (FMCW) light detection and ranging (LiDAR) systems provide high-resolution anti-interference distance and velocity measurements without fast electronics or high optical power but typically require expensive narrow-linewidth lasers with complex feedback circuits. Instead, we report on linearizing the laser chirp by using iterative learning pre-distortion of the laser drive waveform, thus reducing the need for...
