“…The original LIDAR (figure 1(b)) based on a semiconductor (GaAlAs) laser was specifically designed to meet eye safety protocols [14]. Conventional LIDARs operate with laser pulses of high energy to improve the remote sensing sensitivity and range limits.…”

For the first time, we monitored the Elbrus volcano activity detecting volcanic gases emanating through pores using an unique eye-safe LIDAR system. A highly sensitive eye-safe LIDAR system was developed for monitoring the fracture-emitted aerosol, which is transported by volcanic gases inside a hot tunnel near the Elbrus Mountain. The developed LIDAR is based on a diode laser (transmitter, 910 nm, 3 ns, <1 µJ cm−2) and a single-photon avalanche photodiode (detector). From August to October 2019, within the first months of the LIDAR monitoring, we have detected a two-fold decrease in the fracture-emitted aerosol emanation, while other parameters in the tunnel remained relatively stable (radon concentration, air temperature and humidity changed less than by 1%). A significant correlation between the LIDAR signal of volcanic aerosol and the Earth’s crust deformation measured by the laser strainmeter located nearby was found. Based on our preliminary experiments we consider the new LIDAR system as a sensitive, economical and robust instrument for Earth’s crust deformation and volcanic activity monitoring and eruption precursor observation.

“…Nowadays, the blossoming of unmanned aircraft vehicle (UAV) development has completely changed the exploitation costs [14,15]. The drop in UAV exploitation costs triggered a renaissance in LIDAR instrument development [16][17][18][19][20][21][22][23][24][25]. However, modern UAVs can carry only a few kg weight of compact sizes (10 × 10 × 10 cm 3 ) and low power consumption (<50 W), so the developed LIDAR instruments have to fit these requirements.…”

Fluorescence Mapping of Agricultural Fields Utilizing Drone-Based LIDAR

A compact and low-weight LIDAR instrument has been developed for laser-induced fluorescence spectroscopy sensing of maize fields. Fluorescence LIDAR had to be installed on a small industrial drone so that its mass was <2 kg and power consumption was <5 W. The LIDAR instrument utilized a continuous wave diode laser (405 nm, 150 mW) for inducing fluorescence and a small spectrometer for backscattered photons acquisition. For field testing, the LIDAR instrument was installed on a quadcopter for remote sensing of plants in a maize field in three periods of the plant’s life. The obtained fluorescence signal maps have demonstrated that the average chlorophyll content is rather non-uniform over the field and tends to increase through the plant vegetation cycle. Field tests proved the feasibility and perspectives of autonomous LIDAR sensing of agricultural fields from drones for the detection and location of plants under stress.
