Abstract: Mutual interference of vehicular laser radar causes serious performance reduction of target detection and tracking. From spatial, time and modulation frequency, various possible interference of lidars of pulse and frequency modulated continuous wave method in road environments are studied by simulation. The possibility of the interference is calculated, the features and performance reduction of the interference are analyzed. For the possible interference, using a method of pseudo random noise code to modulate the output amplitude of the continuous wave laser can effectively reduce the probability of interference and ensure the reliable operation of lidar in road environments.

A description is given of a high-speed optical recording system that uses a solid-state yttrium-aluminum garnet Nd3+ laser that generates a train of picosecond laser pulses. It is shown that by registering and temporarily scanning the secondary fluorescence radiation excited by a sequence of picosecond pulses, it is possible to remotely determine the biomass of plants based on a prematurely created bank of laboratory data.
