Abstract

In this study, we aim to develop a mini-lidar system using a LED (Light Emitting Diode) as the light source for near-range measurement. Because LED is small size device and its wavelength is selectable, the LED lidar can be specialized in near-range measurements. In this prototype of the LED mini-lidar, the pulse power is more than 100 mW. And the pulse repetition rate and the pulse width were 112kHz and 10.2ns, respectively. The LED lidar system realized a coaxial optical system by a mirror with a hole. From hard target measurements, we verified receiving characteristics of the LED lidar according to the inversely square of distance from 0 to 100m. We also obtained lidar echoes of the atmosphere in the near range of 50m.
