a 3D Imaging result with a planar target placed at 30.5 m. b Depth distribution histogram. c Theoretical (blue) and measured (red) precisions comparison as the planar target distance increases. d Theoretical precision when the bandwidth of the probe signal is increased from 6 to 30 GHz, and the target is located at the distance from 30 to 240 m. The probe optical power is set to be 15.86 mW. e 3D images of a BIT alphabet model are generated at a data acquisition time of 0.10, 0.25, 0.50, 1.0, 2.0, 5.0, 10.0 and 10.0 s with air turbulences. f Measured precision with different frame counts.
