Abstract

The influence of rain on pulsed LiDAR systems with a miniaturized aperture and small laser beam cross sections was investigated based on two situations deemed critical. First, discrete rain drops appearing very close to the laser aperture could lead to a complete deflection of the laser beam out of the original direction when drop and beam overlap. Our semi-probabilistic, semi-analytical model however indicates that the rate of deflected scan events is negligible. Second, the emitter surface could be, to a greater or lesser extent, covered with drops of various size, degrading the performance. We found an optimum ratio between drop diameter and laser beam diameter, favoring larger laser beams. Also this effect however is, in total, not critical.
