Abstract

We develop a high-precision chaos lidar system using broadband optical chaos from a semiconductor laser subjected to optical feedback. We study how the detector bandwidths, cut-off frequencies, signal-to-noise ratios, and peak sidelobe levels in correlation affect the precision in ranging. With a detector bandwidth of 1600 MHz, a precision of 0.43 mm is achieved from the chaos-modulated pulses with a pulse width of 70 ns. The demonstration and comparison of 3D imaging obtained by waveforms with bandwidths of 1600 and 400 MHz show an enhancement in image quality with broader bandwidths and higher cut-off frequencies.
